Subject: [PATCH v4 0/7] 64bit inode e2fsprogs support

With current hardware clusters faced with the trouble of
creating enough inodes on partitions. Lustre has 0-size
files to store some information about files. Current
MDS disk sizes allow to store large amount of such files, but
EXT4 limits this number to ~4 billions.

Lustre FS has features like DNE to distribute metadata over many targets
(disks), but disks are used not effectively. It would be great to have
ability to store more then ~4 billions inodes on one EXT4 file system.

4th version of patches set. Changes since v3:
* Fixed inodes numbers printing
* INCOMPAT_DIRDATA is enabled on early fsck stage if INCOMPAT_INODE64 is enabled
* 64bit cleanup for superblocks fields: s_inodes_count, free_inodes_count,
  last_orphan, first_error_ino, last_error_ino
* Helpers added to separate patch
* "fid:" prefix added in the original 1/7 patch

Andreas Dilger (2):
  e2fsck: add support for dirdata feature
  tests: add basic tests for dirdata feature

Artem Blagodarenko (4):
  debugfs: 64bit inode support
  ext2fs: Add helper functions to access inode numbers
  ext2fs: add EXT4_FEATURE_INCOMPAT_64INODE support
  e2fsck: INODE64 high part is more important then LUFID

Bobi Jam (1):
  tests: e2fsck -D does not change dirdata
