Subject: [PATCH 08/22] fuse2fs: only flush the cache for the file under directio read
Date: Thu, 17 Jul 2025 16:41:27 -0700	[thread overview]
Message-ID: <175279461178.715479.16479332905031345778.stgit@frogsfrogsfrogs> (raw)
In-Reply-To: <175279460935.715479.15460687085573767955.stgit@frogsfrogsfrogs>

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

We only need to flush the io_channel's cache for the file that's being
read directly, not everything else.
