Merge branch 'for-linus' of git://git./linux/kernel/git/viro/vfs-2.6

* '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()
