'maxItems' equal to the 'items' list length is redundant. 'maxItems' is preferred for a single entry while greater than 1 should have an 'items' list. A meta-schema check for this is pending once these existing cases are fixed.

The binding should use "unevaluatedProperties" instead of "additionalProperties", since it is a SPI device and may have SPI-related Device Tree properties, for instance the "spi-max-frequency" property that is present in the example.

The correct syntax for JSON pointers begins with a '/' after the '#'. Without a '/', the string should be interpreted as a subschema identifier. The jsonschema module currently doesn't handle subschema identifiers and incorrectly allows JSON pointers to begin without a '/'.

Pull tracing updates from Steven Rostedt: "The major update to this release is that there's a new arch config option called CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS. Currently, only x86_64 enables it. All the ftrace callbacks now take a struct ftrace_regs instead of a struct pt_regs. If the architecture has HAVE_DYNAMIC_FTRACE_WITH_ARGS enabled, then the ftrace_regs will have enough information to read the arguments of the function being traced, as well as access to the stack pointer. This way, if a user (like live kernel patching) only cares about the arguments, then it can avoid using the heavier weight "regs" callback, that puts in enough information in the struct ftrace_regs to simulate a breakpoint exception (needed for kprobes). A new config option that audits the timestamps of the ftrace ring buffer at most every event recorded. Ftrace recursion protection has been cleaned up to move the protection to the callback itself (this saves on an extra function call for those callbacks). Perf now handles its own RCU protection and does not depend on ftrace to do it for it (saving on that extra function call). New debug option to add "recursed_functions" file to tracefs that lists all the places that triggered the recursion protection of the function tracer. This will show where things need to be fixed as recursion slows down the function tracer. The eval enum mapping updates done at boot up are now offloaded to a work queue, as it caused a noticeable pause on slow embedded boards. Various clean ups and last minute fixes" * tag 'trace-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (33 commits) tracing: Offload eval map updates to a work queue Revert: "ring-buffer: Remove HAVE_64BIT_ALIGNED_ACCESS" ring-buffer: Add rb_check_bpage in __rb_allocate_pages ring-buffer: Fix two typos in comments tracing: Drop unneeded assignment in ring_buffer_resize() tracing: Disable ftrace selftests when any tracer is running seq_buf: Avoid type mismatch for seq_buf_init ring-buffer: Fix a typo in function description ring-buffer: Remove obsolete rb_event_is_commit() ring-buffer: Add test to validate the time stamp deltas ftrace/documentation: Fix RST C code blocks tracing: Clean up after filter logic rewriting tracing: Remove the useless value assignment in test_create_synth_event() livepatch: Use the default ftrace_ops instead of REGS when ARGS is available ftrace/x86: Allow for arguments to be passed in to ftrace_regs by default ftrace: Have the callbacks receive a struct ftrace_regs instead of pt_regs MAINTAINERS: assign ./fs/tracefs to TRACING tracing: Fix some typos in comments ftrace: Remove unused varible 'ret' ring-buffer: Add recording of ring buffer recursion into recursed_functions ...

Pull modules updates from Jessica Yu: "Summary of modules changes for the 5.11 merge window: - Fix a race condition between systemd/udev and the module loader. The module loader was sending a uevent before the module was fully initialized (i.e., before its init function has been called). This means udev can start processing the module uevent before the module has finished initializing, and some udev rules expect that the module has initialized already upon receiving the uevent. This resulted in some systemd mount units failing if udev processes the event faster than the module can finish init. This is fixed by delaying the uevent until after the module has called its init routine. - Make the linker array sections for kernel params and module version attributes more robust by switching to use the alignment of the type in question. Namely, linker section arrays will be constructed using the alignment required by the struct (using __alignof__()) as opposed to a specific value such as sizeof(void *) or sizeof(long). This is less likely to cause breakages should the size of the type ever change (Johan Hovold) - Fix module state inconsistency by setting it back to GOING when a module fails to load and is on its way out (Miroslav Benes) - Some comment and code cleanups (Sergey Shtylyov)" * tag 'modules-for-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux: module: delay kobject uevent until after module init call module: drop semicolon from version macro init: use type alignment for kernel parameters params: clean up module-param macros params: use type alignment for kernel parameters params: drop redundant "unused" attributes module: simplify version-attribute handling module: drop version-attribute alignment module: fix comment style module: add more 'kernel-doc' comments module: fix up 'kernel-doc' comments module: only handle errors with the *switch* statement in module_sig_check() module: avoid *goto*s in module_sig_check() module: merge repetitive strings in module_sig_check() module: set MODULE_STATE_GOING state when a module fails to load -

Pull f2fs updates from Jaegeuk Kim: "In this round, we've made more work into per-file compression support. For example, F2FS_IOC_GET | SET_COMPRESS_OPTION provides a way to change the algorithm or cluster size per file. F2FS_IOC_COMPRESS | DECOMPRESS_FILE provides a way to compress and decompress the existing normal files manually. There is also a new mount option, compress_mode=fs|user, which can control who compresses the data. Chao also added a checksum feature with a mount option so that we are able to detect any corrupted cluster. In addition, Daniel contributed casefolding with encryption patch, which will be used for Android devices. Summary: Enhancements: - add ioctls and mount option to manage per-file compression feature - support casefolding with encryption - support checksum for compressed cluster - avoid IO starvation by replacing mutex with rwsem - add sysfs, max_io_bytes, to control max bio size Bug fixes: - fix use-after-free issue when compression and fsverity are enabled - fix consistency corruption during fault injection test - fix data offset for lseek - get rid of buffer_head which has 32bits limit in fiemap - fix some bugs in multi-partitions support - fix nat entry count calculation in shrinker - fix some stat information And, we've refactored some logics and fix minor bugs as well" * tag 'f2fs-for-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (36 commits) f2fs: compress: fix compression chksum f2fs: fix shift-out-of-bounds in sanity_check_raw_super() f2fs: fix race of pending_pages in decompression f2fs: fix to account inline xattr correctly during recovery f2fs: inline: fix wrong inline inode stat f2fs: inline: correct comment in f2fs_recover_inline_data f2fs: don't check PAGE_SIZE again in sanity_check_raw_super() f2fs: convert to F2FS_*_INO macro f2fs: introduce max_io_bytes, a sysfs entry, to limit bio size f2fs: don't allow any writes on readonly mount f2fs: avoid race condition for shrinker count f2fs: add F2FS_IOC_DECOMPRESS_FILE and F2FS_IOC_COMPRESS_FILE f2fs: add compress_mode mount option f2fs: Remove unnecessary unlikely() f2fs: init dirty_secmap incorrectly f2fs: remove buffer_head which has 32bits limit f2fs: fix wrong block count instead of bytes f2fs: use new conversion functions between blks and bytes f2fs: rename logical_to_blk and blk_to_logical f2fs: fix kbytes written stat for multi-device case ...

The indirect block cleanup may cause control messages to be sent if offloaded flows are present. However, by the time the flower app cleanup callback is called txbufs are no longer available and attempts to send control messages result in a NULL-pointer dereference in nfp_ctrl_tx_one(). This problem may be resolved by moving the indirect block cleanup to the stop callback, where txbufs are still available. As suggested by Jakub Kicinski and Louis Peens.

When sendmsg() needs to wait for memory, the pending data is not updated. That causes a drift in forward memory allocation, leading to stall and/or warnings at socket close time.

When multiple subflows are active, we can receive a window update on subflow with no write space available. MPTCP will try to push frames on such subflow and will fail. Pending frames will be pushed only after receiving a window update on a subflow with some wspace available. Overall the above could lead to suboptimal aggregate bandwidth usage. Instead, we should try to push pending frames as soon as the subflow reaches both conditions mentioned above. We can finally enable self-tests with asymmetric links, as the above makes them finally pass. Fixes: 6f8a612a ("mptcp: keep track of advertised windows right edge") Reviewed-by:

Commit 991fcb77 ("drm/edid: Fix uninitialized variable in drm_cvt_modes()") just replaced one warning with another. The original warning about a possibly uninitialized variable was due to the compiler not being smart enough to see that the case statement actually enumerated all possible cases. And the initial fix was just to add a "default" case that had a single "unreachable()", just to tell the compiler that that situation cannot happen. However, that doesn't actually fix the fundamental reason for the problem: the compiler still doesn't see that the existing case statements enumerate all possibilities, so the compiler will still generate code to jump to that unreachable case statement. It just won't complain about an uninitialized variable any more. So now the compiler generates code to our inline asm marker that we told it would not fall through, and end end result is basically random. We have created a bridge to nowhere. And then, depending on the random details of just exactly what the compiler ends up doing, 'objtool' might end up complaining about the conditional branches (for conditions that cannot happen, and that thus will never be taken - but if the compiler was not smart enough to figure that out, we can't expect objtool to do so) going off in the weeds. So depending on how the compiler has laid out the result, you might see something like this: drivers/gpu/drm/drm_edid.o: warning: objtool: do_cvt_mode() falls through to next function drm_mode_detailed.isra.0() and now you have a truly inscrutable warning that makes no sense at all unless you start looking at whatever random code the compiler happened to generate for our bare "unreachable()" statement. IOW, don't use "unreachable()" unless you have an _active_ operation that generates code that actually makes it obvious that something is not reachable (ie an UD instruction or similar). Solve the "compiler isn't smart enough" problem by just marking one of the cases as "default", so that even when the compiler doesn't otherwise see that we've enumerated all cases, the compiler will feel happy and safe about there always being a valid case that initializes the 'width' variable. This also generates better code, since now the compiler doesn't generate comparisons for five different possibilities (the four real ones and the one that can't happen), but just for the three real ones and "the rest" (which is that last one). A smart enough compiler that sees that we cover all the cases won't care.
