Alien device is a device in fs_devices list having a different fsid than
the expected fsid. This patch set fixes issues found due to the same.
Patch1: is a cleanup patch, not related.
Patch2: fixes the missing device not missing in the userland, by
hardening the function btrfs_open_one_device().
Patch3: fixes failing to mount a degraded RAID1 (but it can apply
to RAID5/6/10 as well), by hardening the function
btrfs_free_extra_devids().
Patch4: eliminates the source of the alien device in the fs_devices.
Anand Jain (4):
btrfs: drop useless goto in open_fs_devices
btrfs: delete identified alien device in open_fs_devices
btrfs: include non-missing as a qualifier for the latest_bdev
btrfs: free alien device due to device add
