Fast forward almost a # decade, and latent bugs in the code converting this hack from freeze # flags to freeze locks combine with lockdep bugs to make this reproduce # frequently enough to notice page faults racing with freeze. # # Since the hack is unnecessary and causes thread race errors, just get # rid of it completely. Making this kind of vfs change midway through a # cycle makes me nervous, but a large enough number of the usual # VFS/ext4/XFS/btrfs suspects have said this looks good and solves a # real problem vector. # # And once that removal is done, __sb_start_write is now simple enough # that it becomes possible to refactor the function into smaller, # simpler static inline helpers in linux/fs.h. The cleanup is # straightforward. # # Summary: # # - Finally remove the "convert to trylock" weirdness in the fs freezer # code. It was necessary 10 years ago to deal with nested # transactions in XFS, but we've long since removed that; and now # this is causing subtle race conditions when lockdep goes offline # and sb_start_* aren't prepared to retry a trylock failure. # # - Minor cleanups of the sb_start_* fs freeze helpers" # # * tag 'vfs-5.10-fixes-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: # vfs: move __sb_{start,end}_write* to fs.h # vfs: separate __sb_start_write into blocking and non-blocking helpers # vfs: remove lockdep bogosity in __sb_start_write # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux-ld --version # < git log --format=%s --max-count=1 f01c30de86f1047e9bae1b1b1417b0ce8dcd15b1 # < make -s -j 120 ARCH=ia64 O=/kisskb/build/linus_ia64-defconfig_ia64-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux- defconfig arch/ia64/configs/generic_defconfig:58:warning: override: reassigning to symbol ATA arch/ia64/configs/generic_defconfig:59:warning: override: reassigning to symbol ATA_PIIX # make -s -j 120 ARCH=ia64 O=/kisskb/build/linus_ia64-defconfig_ia64-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] In file included from /kisskb/src/arch/ia64/include/uapi/asm/intrinsics.h:22:0, from /kisskb/src/arch/ia64/include/asm/intrinsics.h:11, from /kisskb/src/arch/ia64/include/asm/timex.h:14, from /kisskb/src/include/linux/timex.h:65, from /kisskb/src/include/linux/time32.h:13, from /kisskb/src/include/linux/time.h:73, from /kisskb/src/fs/nfs/read.c:11: /kisskb/src/fs/nfs/read.c: In function 'nfs_read_completion': /kisskb/src/arch/ia64/include/uapi/asm/cmpxchg.h:57:2: warning: value computed is not used [-Wunused-value] ((__typeof__((ptr))) __xchg((unsigned long) (x), (ptr), sizeof((ptr)))) ^ /kisskb/src/fs/nfs/read.c:196:5: note: in expansion of macro 'xchg' xchg(&nfs_req_openctx(req)->error, error); ^ /kisskb/src/fs/nfs/read.c: In function 'nfs_readpage': /kisskb/src/arch/ia64/include/uapi/asm/cmpxchg.h:57:2: warning: value computed is not used [-Wunused-value] ((__typeof__((ptr))) __xchg((unsigned long) (x), (ptr), sizeof((ptr)))) ^ /kisskb/src/fs/nfs/read.c:355:2: note: in expansion of macro 'xchg' xchg(&ctx->error, 0); ^ No errors detected in 22330 functions.
