[PATCH] nfsd4: reference count struct nfs4_file
Add a struct kref to each nfs4_file and take a reference to it from each
stateid and delegation that refers to it. The atomicity guarantees are
overkill given that all this stuff is done under the single nfsd4 state lock,
but a) we'd like finer-grained locking some day, and b) this simplifies the
cleanup of the structures a bit, something that has previously been a bit
complicated and bug-prone.
