gfs2: make gfs2_glock.gl_owner_pid be a struct pid *
The gl_owner_pid field is used to get the lock owning task by its pid, so make it in a proper manner, i.e. by using the struct pid pointer and pid_task() function. The pid_task() becomes exported for the gfs2 module. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Cc: "Eric W.
