Subject: [for-6.13 PATCH 14/19] nfsd: nfsd_file_acquire_local no longer returns GC'd nfsd_file
Date: Fri, 8 Nov 2024 18:39:57 -0500 [thread overview]
Message-ID: <20241108234002.16392-15-snitzer@kernel.org> (raw)
In-Reply-To: <20241108234002.16392-1-snitzer@kernel.org>
Now that LOCALIO no longer leans on NFSD's filecache for caching open
files (and instead uses NFS client-side open nfsd_file caching) there
is no need to use NFSD filecache's GC feature. Avoiding GC will speed
up nfsd_file initial opens.
