This series implements xfs inode data inlining feature. Refered below link during development: https://marc.info/?l=linux-xfs&m=120493585731509&w=2 How it works: - the data inlining happens at: write_iter: for DIO/DAX write writeback: for buffered write - extents to local format conversion is done in writeback but not in write_iter - local to extents format conversion is done in the write_iter and writeback - log the whole inode (core/data) on extents to local conversion - add a new mkfs.xfs option to enable data inline feature How to test: mkfs.xfs -f -i size=2048,inline=1 -m crc=1,finobt=1,rmapbt=1,reflink=1 /dev/sdX mount /dev/sdX mnt_pnt Test results: mkfs.xfs -f -i size=2048,inline=1 -m crc=1,finobt=1,rmapbt=1,reflink=1 /dev/sdb mkfs.xfs -f -i size=2048 -m crc=1,finobt=1,rmapbt=1,reflink=1 /dev/sdd mount /dev/sdb /mnt/sdb mount /dev/sdd /mnt/sdd Copy the linux v4.18-rc3 source code to /mnt/sdb and /mnt/sdd respectively: Filesystem Size Used Avail Use% Mounted on /dev/sdb 10G 2.4G 7.7G 24% /mnt/sdb /dev/sdd 10G 3.1G 6.9G 31% /mnt/sdd mkfs.xfs -f -i size=2048,inline=1 -m crc=1,finobt=1,rmapbt=1,reflink=1 /dev/sdc mkfs.xfs -f -i size=2048 -m crc=1,finobt=1,rmapbt=1,reflink=1 /dev/sde mount /dev/sdc /mnt/sdc mount /dev/sde /mnt/sde Build the v4.18-rc3 kernel on /dev/sdc and /dev/sde respectively: make x86_64_defconfig Filesystem Size Used Avail Use% Mounted on /dev/sdc 10G 689M 9.4G 7% /mnt/sdc /dev/sde 10G 694M 9.4G 7% /mnt/sde Kernel part: 0001-xfs-introduce-inline-data-superblock-feature-bit.patch 0002-xfs-introduce-extents-to-local-conversion-helper.patch 0003-xfs-convert-inode-from-extents-to-local-format.patch 0004-xfs-implement-inline-data-read-write-code.patch 0005-xfs-consider-the-local-format-inode-in-misc-operatio.patch 0006-xfs-fix-imbalanced-locking.patch 0007-xfs-return-non-zero-blocks-for-inline-data.patch 0008-xfs-skip-local-format-inode-for-reflinking.patch fs/xfs/libxfs/xfs_bmap.c | 78 +++++++++++++++++++++++++++++++----- fs/xfs/libxfs/xfs_bmap.h | 4 ++ fs/xfs/libxfs/xfs_format.h | 10 ++++- fs/xfs/libxfs/xfs_fs.h | 1 + fs/xfs/libxfs/xfs_inode_buf.c | 6 --- fs/xfs/libxfs/xfs_sb.c | 2 + fs/xfs/scrub/inode.c | 2 +- fs/xfs/xfs_aops.c | 60 ++++++++++++++++++++++++++++ fs/xfs/xfs_bmap_util.c | 11 +++++- fs/xfs/xfs_file.c | 244 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++- fs/xfs/xfs_inode.c | 20 +++++++--- fs/xfs/xfs_inode_item.c | 5 ++- fs/xfs/xfs_ioctl.c | 5 ++- fs/xfs/xfs_iomap.c | 5 ++- fs/xfs/xfs_iops.c | 8 +++- fs/xfs/xfs_log_recover.c | 3 +- fs/xfs/xfs_reflink.c | 6 +++ 17 files changed, 437 insertions(+), 33 deletions(-) xfsprogs part: 0001-xfsprogs-add-inode-inline-data-support.patch growfs/xfs_growfs.c | 14 +++++++++----- libxfs/xfs_format.h | 4 +++- libxfs/xfs_fs.h | 1 + mkfs/xfs_mkfs.c | 20 +++++++++++++++++--- 4 files changed, 30 insertions(+), 9 deletions(-) Thanks Shan Hai -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
