lockd: Fix invalid lockowner cast after vfs_test_lock
[ Upstream commit cd2d644ddba183ec7b451b7c20d5c7cc06fcf0d7 ]
After calling vfs_test_lock() the pointer to a conflicting lock can be
returned, and that lock is not guarunteed to be owned by nlm. In that
case, we cannot cast it to struct nlm_lockowner. Instead return the pid
of that conflicting lock.
Fixes: 646d73e91b42 ("lockd: Show pid of lockd for remote locks")
