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-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 f01c30de86f1047e9bae1b1b1417b0ce8dcd15b1 # < make -s -j 48 ARCH=arm64 O=/kisskb/build/linus_arm64-defconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- defconfig # < make -s -j 48 ARCH=arm64 O=/kisskb/build/linus_arm64-defconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- help # make -s -j 48 ARCH=arm64 O=/kisskb/build/linus_arm64-defconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- olddefconfig # make -s -j 48 ARCH=arm64 O=/kisskb/build/linus_arm64-defconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- /kisskb/src/arch/arm64/boot/dts/broadcom/stingray/stingray-usb.dtsi:7.3-14: Warning (dma_ranges_format): /usb:dma-ranges: empty "dma-ranges" property but its #address-cells (1) differs from / (2) /kisskb/src/arch/arm64/boot/dts/broadcom/stingray/stingray-usb.dtsi:7.3-14: Warning (dma_ranges_format): /usb:dma-ranges: empty "dma-ranges" property but its #size-cells (1) differs from / (2) /kisskb/src/arch/arm64/boot/dts/broadcom/stingray/stingray-usb.dtsi:7.3-14: Warning (dma_ranges_format): /usb:dma-ranges: empty "dma-ranges" property but its #address-cells (1) differs from / (2) /kisskb/src/arch/arm64/boot/dts/broadcom/stingray/stingray-usb.dtsi:7.3-14: Warning (dma_ranges_format): /usb:dma-ranges: empty "dma-ranges" property but its #size-cells (1) differs from / (2) /kisskb/src/arch/arm64/boot/dts/broadcom/stingray/stingray-usb.dtsi:7.3-14: Warning (dma_ranges_format): /usb:dma-ranges: empty "dma-ranges" property but its #address-cells (1) differs from / (2) /kisskb/src/arch/arm64/boot/dts/broadcom/stingray/stingray-usb.dtsi:7.3-14: Warning (dma_ranges_format): /usb:dma-ranges: empty "dma-ranges" property but its #size-cells (1) differs from / (2) /kisskb/src/arch/arm64/boot/dts/qcom/ipq6018.dtsi:185.3-14: Warning (dma_ranges_format): /soc:dma-ranges: empty "dma-ranges" property but its #address-cells (1) differs from / (2) /kisskb/src/arch/arm64/boot/dts/qcom/ipq6018.dtsi:185.3-14: Warning (dma_ranges_format): /soc:dma-ranges: empty "dma-ranges" property but its #size-cells (1) differs from / (2) Completed OK # rm -rf /kisskb/build/linus_arm64-defconfig_arm64-gcc8 # Build took: 0:07:03.539689
