Trond Myklebust 34681aeddc NFS: nfsiod should not block forever in mempool_alloc()
[ Upstream commit 515dcdcd48 ]

The concern is that since nfsiod is sometimes required to kick off a
commit, it can get locked up waiting forever in mempool_alloc() instead
of failing gracefully and leaving the commit until later.

Try to allocate from the slab first, with GFP_KERNEL | __GFP_NORETRY,
then fall back to a non-blocking attempt to allocate from the memory
pool.
