Subject: [PATCH 29/61] xfs: push perags through the ag reservation callouts
Date: Wed, 15 Sep 2021 16:09:13 -0700	[thread overview]
Message-ID: <163174735301.350433.10174246477569374371.stgit@magnolia> (raw)
In-Reply-To: <163174719429.350433.8562606396437219220.stgit@magnolia>

From: Dave Chinner <dchinner@redhat.com>

Source kernel commit: 30933120ad79f4549d6e364df7eda474cc0d9c65

We currently pass an agno from the AG reservation functions to the
individual feature accounting functions, which in future may have to
do perag lookups to access per-AG state. Instead, pre-emptively
plumb the perag through from the highest AG reservation layer to the
feature callouts so they won't have to look it up again.
