As congestion is no longer tracked, congestion_wait() is effectively equivalent to io_schedule_timeout(). So introduce f2fs_io_schedule_timeout() which sets TASK_UNINTERRUPTIBLE and call that instead. Link: https://lkml.kernel.org/r/164549983744.9187.6425865370954230902.stgit@noble.brownSigned-off-by:

These functions are no longer useful as no BDIs report congestions any more. Removing the test on bdi_write_contested() in current_may_throttle() could cause a small change in behaviour, but only when PF_LOCAL_THROTTLE is set. So replace the calls by 'false' and simplify the code - and remove the functions.

inode_congested() reports if the backing-device for the inode is congested. No bdi reports congestion any more, so this always returns 'false'. So remove inode_congested() and related functions, and remove the call sites, assuming that inode_congested() always returns 'false'.

The bdi congestion tracking in not widely used and will be removed. CEPHfs is one of a small number of filesystems that uses it, setting just the async (write) congestion flags at what it determines are appropriate times. The only remaining effect of the async flag is to cause (some) WB_SYNC_NONE writes to be skipped. So instead of setting the flag, set an internal flag and change: - .writepages to do nothing if WB_SYNC_NONE and the flag is set - .writepage to return AOP_WRITEPAGE_ACTIVATE if WB_SYNC_NONE and the flag is set. The writepages change causes a behavioural change in that pageout() can now return PAGE_ACTIVATE instead of PAGE_KEEP, so SetPageActive() will be called on the page which (I think) wil further delay the next attempt at writeout. This might be a good thing. Link: https://lkml.kernel.org/r/164549983739.9187.14895675781408171186.stgit@noble.brownSigned-off-by:

The bdi congestion tracking in not widely used and will be removed. Fuse is one of a small number of filesystems that uses it, setting both the sync (read) and async (write) congestion flags at what it determines are appropriate times. The only remaining effect of the sync flag is to cause read-ahead to be skipped. The only remaining effect of the async flag is to cause (some) WB_SYNC_NONE writes to be skipped. So instead of setting the flags, change: - .readahead to stop when it has submitted all non-async pages for read. - .writepages to do nothing if WB_SYNC_NONE and the flag would be set - .writepage to return AOP_WRITEPAGE_ACTIVATE if WB_SYNC_NONE and the flag would be set. The writepages change causes a behavioural change in that pageout() can now return PAGE_ACTIVATE instead of PAGE_KEEP, so SetPageActive() will be called on the page which (I think) will further delay the next attempt at writeout.

If ->readpages doesn't process all the pages, then it is best to act as though they weren't requested so that a subsequent readahead can try again. So: - remove any 'ahead' pages from the page cache so they can be loaded with ->readahead() rather then multiple ->read()s - update the file_ra_state to reflect the reads that were actually submitted. This allows ->readpages() to abort early due e.g. to congestion, which will then allow us to remove the inode_read_congested() test from page_Cache_async_ra().

NeilBrown authored
Add some "big-picture" documentation for read-ahead and polish the code to make it fit this documentation. The meaning of ->async_size is clarified to match its name. i.e. Any request to ->readahead() has a sync part and an async part. The caller will wait for the sync pages to complete, but will not wait for the async pages. The first async page is still marked PG_readahead Note that the current function names page_cache_sync_ra() and page_cache_async_ra() are misleading. All ra request are partly sync and partly async, so either part can be empty. A page_cache_sync_ra() request will usually set ->async_size non-zero, implying it is not all synchronous. When a non-zero req_count is passed to page_cache_async_ra(), the implication is that some prefix of the request is synchronous, though the calculation made there is incorrect - I haven't tried to fix it.

Patch series "Remove remaining parts of congestion tracking code", v2. This patch (of 11): Various DOC: sections in gfp.h have subsection headers (~~~) but the place where they are included in mm-api.rst does not have section, only chapters. So convert to section headers (---) to avoid confusion. Specifically if sections are added later in mm-api.rst, an error results.

Ever since these macros were introduced in commit b56c0d89 ("kthread: implement kthread_worker"), there has been precisely one user (commit 4d115420, "NVMe: Async IO queue deletion"), and that user went away in 2016 with db3cbfff ("NVMe: IO queue deletion re-write"). Apart from being unused, these macros are also awkward to use (which may contribute to them not being used): Having a way to statically (or on-stack) allocating the storage for the struct kthread_worker itself doesn't help much, since obviously one needs to have some code for actually _spawning_ the worker thread, which must have error checking. And these days we have the kthread_create_worker() interface which both allocates the struct kthread_worker and spawns the kthread.

The commit in Fixes started adding INT3 after RETs as a mitigation against straight-line speculation. The fastop SETcc implementation in kvm's insn emulator uses macro magic to generate all possible SETcc functions and to jump to them when emulating the respective instruction. However, it hardcodes the size and alignment of those functions to 4: a three-byte SETcc insn and a single-byte RET. BUT, with SLS, there's an INT3 that gets slapped after the RET, which brings the whole scheme out of alignment: 15: 0f 90 c0 seto %al 18: c3 ret 19: cc int3 1a: 0f 1f 00 nopl (%rax) 1d: 0f 91 c0 setno %al 20: c3 ret 21: cc int3 22: 0f 1f 00 nopl (%rax) 25: 0f 92 c0 setb %al 28: c3 ret 29: cc int3 and this explodes like this: int3: 0000 [#1] PREEMPT SMP PTI CPU: 0 PID: 2435 Comm: qemu-system-x86 Not tainted 5.17.0-rc8-sls #1 Hardware name: Dell Inc.

Before this patch, the symbol end address fixup to be called, needed two conditions being met: if (prev->end == prev->start && prev->end != curr->start) Where "prev->end == prev->start" means that prev is zero-long (and thus needs a fixup) and "prev->end != curr->start" means that fixup hasn't been applied yet However, this logic is incorrect in the following situation: *curr = {rb_node = {__rb_parent_color = 278218928, rb_right = 0x0, rb_left = 0x0}, start = 0xc000000000062354, end = 0xc000000000062354, namelen = 40, type = 2 '\002', binding = 0 '\000', idle = 0 '\000', ignore = 0 '\000', inlined = 0 '\000', arch_sym = 0 '\000', annotate2 = false, name = 0x1159739e "kprobe_optinsn_page\t[__builtin__kprobes]"} *prev = {rb_node = {__rb_parent_color = 278219041, rb_right = 0x109548b0, rb_left = 0x109547c0}, start = 0xc000000000062354, end = 0xc000000000062354, namelen = 12, type = 2 '\002', binding = 1 '\001', idle = 0 '\000', ignore = 0 '\000', inlined = 0 '\000', arch_sym = 0 '\000', annotate2 = false, name = 0x1095486e "optinsn_slot"} In this case, prev->start == prev->end == curr->start == curr->end, thus the condition above thinks that "we need a fixup due to zero length of prev symbol, but it has been probably done, since the prev->end == curr->start", which is wrong. After the patch, the execution path proceeds to arch__symbols__fixup_end function which fixes up the size of prev symbol by adding page_size to its end offset.

Once s_root is set, genric_shutdown_super() will be called if fill_super() fails. That means, we will call ocfs2_dismount_volume() twice in such case, which can lead to kernel crash. Fix this issue by initializing filecheck kobj before setting s_root.
