Subject: [PATCH 16/20] xfs: queue inodegc worker immediately on backlog
Date: Thu, 29 Jul 2021 11:45:21 -0700 [thread overview]
Message-ID: <162758432174.332903.11780876054270545225.stgit@magnolia> (raw)
In-Reply-To: <162758423315.332903.16799817941903734904.stgit@magnolia>
From: Darrick J. Wong <djwong@kernel.org>
If an AG has hit the maximum number of inodes that it can queue for
inactivation, schedule the worker immediately.
