From 36029dee382a20cf515494376ce9f0d5949944eb Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Thu, 7 Jul 2022 19:13:21 +1000 Subject: [PATCH] xfs: make is_log_ag() a first class helper We check if an ag contains the log in many places, so make this a first class XFS helper by lifting it to fs/xfs/libxfs/xfs_ag.h and renaming it xfs_ag_contains_log(). The convert all the places that check if the AG contains the log to use this helper. Signed-off-by: Dave Chinner Reviewed-by: Christoph Hellwig Reviewed-by: Darrick J.
