* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6: Minix: Clean up left over label fix truncate inode time modification breakage fix setattr error handling in sysfs, configfs fcntl: return -EFAULT if copy_to_user fails wrong type for 'magic' argument in simple_fill_super() fix the deadlock in qib_fs mqueue doesn't need make_bad_inode()
