From c918d42a27a9be0d78be490997d16d79cd5b9193 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 3 Feb 2014 12:13:09 -0500 Subject: locks: make /proc/locks show IS_FILE_PVT locks as type "FLPVT" In a later patch, we'll be adding a new type of lock that's owned by the struct file instead of the files_struct. Those sorts of locks will be flagged with a new FL_FILE_PVT flag. Report these types of locks as "FLPVT" in /proc/locks to distinguish them from "classic" POSIX locks. Acked-by: J.
