Merge branch 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6
* 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6: vfs: make unlink() and rmdir() return ENOENT in preference to EROFS lmLogOpen() broken failure exit usb: remove bad dput after dentry_unhash more conservative S_NOSEC handling
