Subject: [PATCH 15/15] xfs: use separate btree cursor cache for each btree type
Date: Tue, 12 Oct 2021 16:33:56 -0700	[thread overview]
Message-ID: <163408163634.4151249.5333674876821248862.stgit@magnolia> (raw)
In-Reply-To: <163408155346.4151249.8364703447365270670.stgit@magnolia>

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

Now that we have the infrastructure to track the max possible height of
each btree type, we can create a separate slab cache for cursors of each
type of btree.  For smaller indices like the free space btrees, this
means that we can pack more cursors into a slab page, improving slab
utilization.
