NeilBrown f859788868 NFS: fix disabling of swap ... [ Upstream commit 5bab56fff5 ] When swap is activated to a file on an NFSv4 mount we arrange that the state manager thread is always present as starting a new thread requires memory allocations that might block waiting for swap. Unfortunately the code for allowing the state manager thread to exit when swap is disabled was not tested properly and does not work. This can be seen by examining /proc/fs/nfsfs/servers after disabling swap and unmounting the filesystem. The servers file will still list one entry. Also a "ps" listing will show the state manager thread is still present. There are two problems. 1/ rpc_clnt_swap_deactivate() doesn't walk up the ->cl_parent list to find the primary client on which the state manager runs. 2/ The thread is not woken up properly and it immediately goes back to sleep without checking whether it is really needed. Using nfs4_schedule_state_manager() ensures a proper wake-up.
