From: Alexander Aring <aahringo@xxxxxxxxxx>
commit 92655fbda5c05950a411eaabc19e025e86e2a291 upstream.
The GETLK pid values have all been negated since commit 9d5b86ac13c5
("fs/locks: Remove fl_nspid and use fs-specific l_pid for remote locks").
Revert this for local pids, and leave in place negative pids for remote
owners.
