This allows the Lustre File IDentifier to be accessed in an efficient manner, and would be useful for expanding a filesystem to allow more than 2^32 inodes in the future. Include this patches: e2fsck: e2fsck -D does not change dirdata content Fix dir optimization to preserve dirdata content for dot and dotdot entries. Lustre-bug: https://jira.hpdd.intel.com/browse/LU-1774 Signed-off-by: Bobi Jam Change-Id: Iae190794da75a2080a8e5cc5b95a49e0c894f72f e2fsprogs: Consider DIRENT_LUFID flag in link_proc(). While adding the new file entry in directory block, link_proc() calculates minimum record length of the existing directory entry without considering the dirent data size and which leads to corruption. Changed the code to use EXT2_DIR_REC_LEN() which will return correct record length including dirent data size. Lustre-bug: https://jira.hpdd.intel.com/browse/LU-2462 Signed-off-by: Manisha Salve Change-Id: Ic593c558c47a78183143ec8e99d8385ac94d06f7 libext2fs, e2fsck: don't use ext2_dir_entry_2 Due to endian issues, do not use ext2_dir_entry_2 because it will have the wrong byte order on directory entries that are swabbed. Instead, use the standard practice of mask-and-shift to access the file_type and dirdata flags.
