[PATCH 0/2] xfs: fix potential integer overflow in sort comparators

[Yuto Ohnuki <ytohnuki@amazon.com>]

Several sort comparators in XFS subtract two uint32_t values and
return the result as int, which can overflow when the difference
exceeds INT_MAX.

Use cmp_int() instead, as was done in commit 362c49098086
("xfs: fix integer overflow in bmap intent sort comparator").

Patch 1 fixes the deferred intent comparators (rmap, extfree, refcount).
Patch 2 fixes the busy extent comparator.

  xfs: fix integer overflow in busy extent sort comparator
