[PATCH 07/12] xfs: use helpers to extract xattr op from opflags

Darrick J. Wong
2024-04-10T00:52:13Z

From: Darrick J. Wong <djwong@kernel.org>

Create helper functions to extract the xattr op from the ondisk xattri
log item and the incore attr intent item. These will get more use in
the patches that follow.
