Use the standard snd_ctl_remove_id() helper function instead of open code. This allows us to reduce the manual card->rwsem lock in the caller side.

snd_ctl_rename() expects that card->controls_rwsem is held in the caller side for avoiding possible races, but actually no one really did that. It's likely because this operation is done usually only at the device initialization where no race can happen. But, it's still safer to take a lock, so we just take the lock inside snd_ctl_rename() like most of other API functions do.

Pull x86 CFI fixes from Peter Zijlstra: "Fix kCFI/FineIBT weaknesses The primary bug Alyssa noticed was that with FineIBT enabled function prologues have a spurious ENDBR instruction: __cfi_foo: endbr64 subl $hash, %r10d jz 1f ud2 nop 1: foo: endbr64 <--- *sadface* This means that any indirect call that fails to target the __cfi symbol and instead targets (the regular old) foo+0, will succeed due to that second ENDBR. Fixing this led to the discovery of a single indirect call that was still doing this: ret_from_fork(). Since that's an assembly stub the compiler would not generate the proper kCFI indirect call magic and it would not get patched. Brian came up with the most comprehensive fix -- convert the thing to C with only a very thin asm wrapper. This ensures the kernel thread boostrap is a proper kCFI call. While discussing all this, Kees noted that kCFI hashes could/should be poisoned to seal all functions whose address is never taken, further limiting the valid kCFI targets -- much like we already do for IBT. So what was a 'simple' observation and fix cascaded into a bunch of inter-related CFI infrastructure fixes" * tag 'x86_urgent_for_6.5_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/cfi: Only define poison_cfi() if CONFIG_X86_KERNEL_IBT=y x86/fineibt: Poison ENDBR at +0 x86: Rewrite ret_from_fork() in C x86/32: Remove schedule_tail_wrapper() x86/cfi: Extend ENDBR sealing to kCFI x86/alternative: Rename apply_ibt_endbr() x86/cfi: Extend {JMP,CAKK}_NOSPEC comment

When the number of responses with status of STATUS_IO_TIMEOUT exceeds a specified threshold (NUM_STATUS_IO_TIMEOUT), we reconnect the connection. But we do not return the mid, or the credits returned for the mid, or reduce the number of in-flight requests. This bug could result in the server->in_flight count to go bad, and also cause a leak in the mids. This change moves the check to a few lines below where the response is decrypted, even of the response is read from the transform header. This way, the code for returning the mids can be reused. Also, the cifs_reconnect was reconnecting just the transport connection before. In case of multi-channel, this may not be what we want to do after several timeouts. Changed that to reconnect the session and the tree too. Also renamed NUM_STATUS_IO_TIMEOUT to a more appropriate name MAX_STATUS_IO_TIMEOUT.

Currently, is_network_name_deleted and it's implementations do not return anything if the network name did get deleted. So the function doesn't fully achieve what it advertizes. Changed the function to return a bool instead. It will now return true if the error returned is STATUS_NETWORK_NAME_DELETED and the share (tree id) was found to be connected. It returns false otherwise. Signed-off-by: Shyam Prasad N <sprasad@microsoft.com> Acked-by: Paulo Alcantara (SUSE) <pc@manguebit.com> Signed-off-by: Steve French <stfrench@microsoft.com>

We used to insert the data commands following a pre-flush to the head of the queue until commit 1e82fadf ("blk-mq: do not do head insertions post-pre-flush commands"). Not doing this seems to cause hangs of such commands on NFS workloads when exported from file systems with SATA SSDs. I have no idea why this would starve these workloads, but doing a semantic revert of this patch (which looks quite different due to various other changes) fixes the hangs.

The ida_alloc_range() function returns negative error codes on error. On success it returns values in the min to max range (inclusive). It never returns more then INT_MAX even if "max" is higher. It never returns values in the 0 to (min - 1) range. The bug is that "min" is an unsigned int so negative error codes will be promoted to high positive values errors treated as success.

Fix to record 0-length data to data_loc in fetch_store_string*() if it fails to get the string data. Currently those expect that the data_loc is updated by store_trace_args() if it returns the error code. However, that does not work correctly if the argument is an array of strings. In that case, store_trace_args() only clears the first entry of the array (which may have no error) and leaves other entries. So it should be cleared by fetch_store_string*() itself. Also, 'dyndata' and 'maxlen' in store_trace_args() should be updated only if it is used (ret > 0 and argument is a dynamic data.)

Pull tracing fixes from Steven Rostedt: - Fix some missing-prototype warnings - Fix user events struct args (did not include size of struct) When creating a user event, the "struct" keyword is to denote that the size of the field will be passed in. But the parsing failed to handle this case. - Add selftest to struct sizes for user events - Fix sample code for direct trampolines. The sample code for direct trampolines attached to handle_mm_fault(). But the prototype changed and the direct trampoline sample code was not updated. Direct trampolines needs to have the arguments correct otherwise it can fail or crash the system. - Remove unused ftrace_regs_caller_ret() prototype. - Quiet false positive of FORTIFY_SOURCE Due to backward compatibility, the structure used to save stack traces in the kernel had a fixed size of 8. This structure is exported to user space via the tracing format file. A change was made to allow more than 8 functions to be recorded, and user space now uses the size field to know how many functions are actually in the stack. But the structure still has size of 8 (even though it points into the ring buffer that has the required amount allocated to hold a full stack. This was fine until the fortifier noticed that the memcpy(&entry->caller, stack, size) was greater than the 8 functions and would complain at runtime about it. Hide this by using a pointer to the stack location on the ring buffer instead of using the address of the entry structure caller field. - Fix a deadloop in reading trace_pipe that was caused by a mismatch between ring_buffer_empty() returning false which then asked to read the data, but the read code uses rb_num_of_entries() that returned zero, and causing a infinite "retry". - Fix a warning caused by not using all pages allocated to store ftrace functions, where this can happen if the linker inserts a bunch of "NULL" entries, causing the accounting of how many pages needed to be off. - Fix histogram synthetic event crashing when the start event is removed and the end event is still using a variable from it - Fix memory leak in freeing iter->temp in tracing_release_pipe() * tag 'trace-v6.5-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Fix memory leak of iter->temp when reading trace_pipe tracing/histograms: Add histograms to hist_vars if they have referenced variables tracing: Stop FORTIFY_SOURCE complaining about stack trace caller ftrace: Fix possible warning on checking all pages used in ftrace_process_locs() ring-buffer: Fix deadloop issue on reading trace_pipe tracing: arm64: Avoid missing-prototype warnings selftests/user_events: Test struct size match cases tracing/user_events: Fix struct arg size match check x86/ftrace: Remove unsued extern declaration ftrace_regs_caller_ret() arm64: ftrace: Add direct call trampoline samples support samples: ftrace: Save required argument registers in sample trampolines

The iocost rely on rq start_time_ns and alloc_time_ns to tell saturation state of the block device. Most of the time request is allocated after rq_qos_throttle() and its alloc_time_ns or start_time_ns won't be affected. But for plug batched allocation introduced by the commit 47c122e3 ("block: pre-allocate requests if plug is started and is a batch"), we can rq_qos_throttle() after the allocation of the request. This is what the blk_mq_get_cached_request() does. In this case, the cached request alloc_time_ns or start_time_ns is much ahead if blocked in any qos ->throttle(). Fix it by setting alloc_time_ns and start_time_ns to now when the allocated request is actually used.
