From c5fd363d771393a7b42bbbe051f30f97d4867a40 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 23 Jul 2012 13:28:37 -0400 Subject: cifs: move file_lock off stack in cifs_push_posix_locks struct file_lock is pretty large, so we really don't want that on the stack in a potentially long call chain. Reorganize the arguments to CIFSSMBPosixLock to eliminate the need for that. Eliminate the get_flag and simply use a non-NULL pLockInfo to indicate that this is a "get" operation. In order to do that, need to add a new loff_t argument for the start_offset.
