This patch set makes files less than ~3.4K store directly in inode block. a) space saving Test with kernel src(without repo data), it can save about 10% space with this patch set; b) performance Test this patch set with iozone, there is no obvious performance difference with the results of disabling this feature. Huajun Li (5): f2fs: Add flags and helpers to support inline data f2fs: Add a new mount option: inline_data f2fs: Add a new function: f2fs_reserve_block() f2fs: Key functions to handle inline data f2fs: Handle inline data read and write fs/f2fs/Makefile | 2 +- fs/f2fs/data.c | 77 ++++++++++++++++++++----- fs/f2fs/f2fs.h | 22 ++++++++ fs/f2fs/file.c | 42 +++++++++++++- fs/f2fs/inline.c | 144 +++++++++++++++++++++++++++++++++++++++++++++++ fs/f2fs/super.c | 8 ++- include/linux/f2fs_fs.h | 8 +++ 7 files changed, 283 insertions(+), 20 deletions(-) create mode 100644 fs/f2fs/inline.c -- 1.7.9.5
