From 70cc6487a4e08b8698c0e2ec935fb48d10490162 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Thu, 22 Feb 2007 18:48:53 -0500 Subject: [PATCH] locks: make ->lock release private data before returning in GETLK case The file_lock argument to ->lock is used to return the conflicting lock when found. There's no reason for the filesystem to return any private information with this conflicting lock, but nfsv4 is. Fix nfsv4 client, and modify locks.c to stop calling fl_release_private for it in this case. Signed-off-by: "J.
