e2fsprogs/e2fsck/problem.h
Theodore Ts'o d4b0ce0316 ChangeLog, problem.c, problem.h, super.c: 
problem.c, problem.h (PR_0_INODE_COUNT_WRONG): Add new problem code.
  super.c (check_super_block): Add check to make sure the total number
  	of inodes is sane, since this can be calculated from the number of
  	groups times the number of inodes per group.  Offer to correct it if
  	it is incorrect.
