6372fb0cc4 btrfs-util: convert O_PATH if necessary, in btrfs quota call (bsc#1205560)
  12e68eb0e5 blockdev-util: move O_PATH fd conversion into btrfs_get_block_device_fd() to shorten things
  bb2bafdc9d btrfs-util: convert to fd_reopen_condition()
  1323232948 fd-util: add new helper fd_reopen_conditional()
- Drop 6000-Revert-tmpfiles-whenever-creating-an-inode-immediate.patch
  It's no more needed as a fix for bsc#1205560 has been queued, see above.
