[RFC PATCH 0/2] xfs: change xfs log item refcount design

[Jeffin Philip]

This patch series is the first of the series where we attempt to convert
the XFS Log item reference counting design to be more generic
compared to the previous type-specific state to fix the "zero
refcount but in AIL means alive" state. The patch series follows
instructions outlined here[1].

Obviously, the wrappers will be integrated in type-specific functions
later on.

No behavioral change as of yet.
