Subject: [patch 09/24] vfs: truncate: dont check immutable twice
Date: Tue, 06 May 2008 11:13:36 +0200 [thread overview]
Message-ID: <20080506091417.195070762@szeredi.hu> (raw)
In-Reply-To: 20080506091327.259950960@szeredi.hu
[-- Attachment #1: truncate_immutable_cleanup.patch --]
[-- Type: text/plain, Size: 739 bytes --]
From: Miklos Szeredi <mszeredi@suse.cz>
vfs_permission(MAY_WRITE) already checked for the inode being
immutable, so no need to repeat it.
