Subject: [PATCH 10/42] xfs: use active perag references for inode allocation
Date: Fri, 10 Feb 2023 09:17:53 +1100 [thread overview]
Message-ID: <20230209221825.3722244-11-david@fromorbit.com> (raw)
In-Reply-To: <20230209221825.3722244-1-david@fromorbit.com>
From: Dave Chinner <dchinner@redhat.com>
Convert the inode allocation routines to use active perag references
or references held by callers rather than grab their own. Also drive
the perag further inwards to replace xfs_mounts when doing
operations on a specific AG.
