Subject: [PATCH 4/6] fuse2fs: enable caching IO manager
Date: Wed, 20 Aug 2025 18:24:18 -0700 [thread overview]
Message-ID: <175573714757.23206.14015594018065840662.stgit@frogsfrogsfrogs> (raw)

From: Darrick J. Wong <djwong@kernel.org>
Enable the new dynamic iocache I/O manager in the fuse server, and turn
off all the other cache control.
