5.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Chuck Lever <chuck.lever@xxxxxxxxxx> [ Upstream commit 08af54b3e5729bc1d56ad3190af811301bdc37a1 ] Now that there are no more callers of nfsd_file_put() that might hold a spin lock, ensure the lockdep infrastructure can catch newly introduced calls to nfsd_file_put() made while a spinlock is held.
