From 1a747ee0cc11a198f9e2435add821bd0dfedb7c1 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Thu, 24 Apr 2008 10:08:22 -0400 Subject: locks: don't call ->copy_lock methods on return of conflicting locks The file_lock structure is used both as a heavy-weight representation of an active lock, with pointers to reference-counted structures, etc., and as a simple container for parameters that describe a file lock. The conflicting lock returned from __posix_lock_file is an example of the latter; so don't call the filesystem or lock manager callbacks when copying to it. This also saves the need for an unnecessary locks_init_lock in the nfsv4 server. Thanks to Trond for pointing out the error. Signed-off-by: J.
