From decf3400879d02d0eafedea52c7f208587be062a Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Mon, 21 May 2012 17:30:08 +0200 Subject: vfs: do_last(): use inode variable Use helper variable instead of path->dentry->d_inode before complete_walk(). This will allow this code to be used in RCU mode.
