CacheFiles: Don't log lookup/create failing with ENOBUFS
David Howells [Thu, 19 Nov 2009 18:12:08 +0000 (18:12 +0000)]
Don't log the CacheFiles lookup/create object routined failing with ENOBUFS as
under high memory load or high cache load they can do this quite a lot.  This
error simply means that the requested object cannot be created on disk due to
lack of space, or due to failure of the backing filesystem to find sufficient
resources.
