H A Dnamei.cf8310c59 Mon Jul 30 02:50:30 CDT 2012 Al Viro <viro@zeniv.linux.org.uk> fix O_EXCL handling for devices

71574865 Tue Jun 05 08:10:14 CDT 2012 Miklos Szeredi <mszeredi@suse.cz> vfs: do_last(): common slow lookup

Make the slow lookup part of O_CREAT and non-O_CREAT opens common.

This allows atomic_open to be hooked into the slow lookup part.
