Re: [PATCH 1/1] btrfs-progs: introduce a proper structure on which cli will call register-device ioctl

[Anand Jain <Anand.Jain@oracle.com>]

I have all 6 patches,

----
e56117f btrfs-progs: optimize btrfs_scan_lblkid() for multiple calls
4d76f5f btrfs-progs: introduce btrfs_register_all_device()
7dd7ef7 btrfs-progs: code optimize cmd_scan_dev() use 
btrfs_register_one_device()
7158fe7 btrfs-progs: open RW to register device using btrfs-control
6bba89f btrfs-progs: introduce a proper structure on which cli will call 
register-device ioctl
df572b7 btrfs-progs: mkfs should be consistent in calling register device
----

you might have only below 3. I tried with that sub-set too but still
it does not fail here.

Thanks, Anand
