Subject: ChangeLog, expanddir.c, ext2fs.h:
X-Git-Tag: E2FSPROGS-1_16~22
X-Git-Url: https://git.whamcloud.com/gitweb?a=commitdiff_plain;h=3a5f8eaa9741f6f14520ddd263a996e2764dd437;p=tools%2Fe2fsprogs.git

ChangeLog, expanddir.c, ext2fs.h:
  ext2fs.h: Add new fields for journalling and define new feature bits
  	used by newer filesystems: IMAGIC_INODES, HAS_JOURNAL, RECOVER.
  expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where we
  	update the inode block count and size files so that the block count
  	field is updated correctly when we create an indirect block.
