e2fsprogs/e2fsck/problem.h
Theodore Ts'o a9ca2016e1 ChangeLog, pass1.c, problem.c, problem.h: 
pass1.c (e2fsck_pass1): Cap the maximum legal size of a file by the
  	limit caused by the fact that i_blocks is in 512 byte units, and that
  	the Linux buffer cache also fundamentally assumes 512 byte sectors.
  	Make sure that the journal inode is a regular file, and when clearing
  	an unused journal inode, make sure the icount db is updated.
  problem.c, problem.h (PR_1_JOURNAL_BAD_MODE): Add new problem code.
ChangeLog, journal.c:
  journal.c (e2fsck_journal_fix_unsupported_super): Remove unused
  	function.  Add FIXME notes to e2fsck_get_journal(), from Andreas
  	Dilger.
