[PATCH v2 0/6] xfs: cleanup key comparing routines

[Fedor Pchelkin <pchelkin@ispras.ru>]

Key comparing routines are currently opencoded with extra casts and
subtractions which is error prone and can be replaced with a neat
cmp_int() helper which is now in a generic header file.

Fedor Pchelkin (6):
  xfs: rename diff_two_keys routines
  xfs: rename key_diff routines
  xfs: refactor cmp_two_keys routines to take advantage of cmp_int()
  xfs: refactor cmp_key_with_cur routines to take advantage of cmp_int()
  xfs: use a proper variable name and type for storing a comparison
    result
  xfs: refactor xfs_btree_diff_two_ptrs() to take advantage of cmp_int()
