Subject: [PATCH 33/37] NFS: nfs_readpage_async() needs to be accessible as a fallback for local caching [ver #34]
Date: Fri, 29 Feb 2008 00:46:30 +0000	[thread overview]
Message-ID: <20080229004630.4142.7485.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <20080229004332.4142.51771.stgit@warthog.procyon.org.uk>

nfs_readpage_async() needs to be non-static so that it can be used as a
fallback for the local on-disk caching should an EIO crop up when reading the
cache.
