NFSv4: Protect the state recovery thread against direct reclaim [ Upstream commit 3e17898aca293a24dae757a440a50aa63ca29671 ] If memory allocation triggers a direct reclaim from the state recovery thread, then we can deadlock. Use memalloc_nofs_save/restore to ensure that doesn't happen. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
