0. modified inode structure -------------------------------------- metadata (e.g., i_mtime, i_ctime, etc) -------------------------------------- direct pointers [0 ~ 873] inline xattrs (200 bytes by default) indirect pointers [0 ~ 4] -------------------------------------- node footer -------------------------------------- 1. setxattr flow - read_all_xattrs copies all the xattrs from inline and xattr node block. - handle xattr entries - write_all_xattrs copies modified xattrs into inline and xattr node block. 2. getxattr flow - read_all_xattrs copies all the xattrs from inline and xattr node block. - check target entries 3. Usage # mount -t f2fs -o inline_xattr $DEV $MNT Once mounted with the inline_xattr option, f2fs marks all the newly created files to reserve an amount of inline xattr space explicitly inside the inode block. Without the mount option, f2fs will not touch any existing files and newly created files as well. Signed-off-by: Jaegeuk Kim <jaegeuk.kim@samsung.com> |
