Message-Id: <1337614220-6174-5-git-send-email-miklos@szeredi.hu> Date: Mon, 21 May 2012 17:30:08 +0200 From: Miklos Szeredi <miklos@...redi.hu> To: viro@...IV.linux.org.uk Cc: linux-fsdevel@...r.kernel.org, linux-kernel@...r.kernel.org, hch@...radead.org, torvalds@...ux-foundation.org, mszeredi@...e.cz Subject: [PATCH 04/16] vfs: do_last(): use inode variable From: Miklos Szeredi <mszeredi@...e.cz> Use helper variable instead of path->dentry->d_inode before complete_walk(). This will allow this code to be used in RCU mode.
