Subject: [for-6.13 PATCH v2 03/15] nfsd: add nfsd_file_{get,put} to 'nfs_to' nfsd_localio_operations
Date: Wed, 13 Nov 2024 22:59:40 -0500	[thread overview]
Message-ID: <20241114035952.13889-4-snitzer@kernel.org> (raw)
In-Reply-To: <20241114035952.13889-1-snitzer@kernel.org>

In later a commit LOCALIO must call both nfsd_file_get and
nfsd_file_put to manage extra nfsd_file references.
