NFS: Fix a deadlock involving nfsreleasefolio()
Wang Zhaolong reports a deadlock involving NFSv4.1 state recovery waiting on kthreadd, which is attempting to reclaim memory by calling nfsreleasefolio(). The latter cannot make progress due to state recovery being needed.
It seems that the only safe thing to do here is to kick off a writeback of the folio, without waiting for completion, or else kicking off an asynchronous commit.
