Specifically, STATX_DIOALIGN works on block devices, and # on regular files when their containing filesystem has implemented # support. # # An interface like this has been requested for years, since the # conditions for when DIO is supported in Linux have gotten increasingly # complex over time. Today, DIO support and alignment requirements can # be affected by various filesystem features such as multi-device # support, data journalling, inline data, encryption, verity, # compression, checkpoint disabling, log-structured mode, etc. # # Further complicating things, Linux v6.0 relaxed the traditional rule # of DIO needing to be aligned to the block device's logical block size; # now user buffers (but not file offsets) only need to be aligned to the # DMA alignment. # # The approach of uplifting the XFS specific ioctl XFS_IOC_DIOINFO was # discarded in favor of creating a clean new interface with statx(). # # For more information, see the individual commits and the man page # update[1]" # # Link: https://lore.kernel.org/r/20220722074229.148925-1-ebiggers@kernel.org [1] # # * tag 'statx-dioalign-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux: # xfs: support STATX_DIOALIGN # f2fs: support STATX_DIOALIGN # f2fs: simplify f2fs_force_buffered_io() # f2fs: move f2fs_force_buffered_io() into file.c # ext4: support STATX_DIOALIGN # fscrypt: change fscrypt_dio_supported() to prepare for STATX_DIOALIGN # vfs: support STATX_DIOALIGN on block devices # statx: add direct I/O alignment information # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 725737e7c21d2d25a4312c2aaa82a52bd03e3126 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_ppc64le_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64le_defconfig # < make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_ppc64le_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_ppc64le_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_ppc64le_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/linus_ppc64le_defconfig_powerpc-gcc5 # Build took: 0:02:12.042795
