[PATCH 0/3] Send: minor cleanups, add RO checks
First two patches are trivial cleanups that I''ve spotted while reading send.c,
can be applied independently.
The third patch contains the important bits, safety checks that the subvolumes
involved in send do not accidentally lose the RO status. I haven''t seen this
documented anywhere that this is mandatory, implied from how I assume send
works. Please let me know if this is

[Request for review] [RFC] Add label support for snapshots and subvols
From: Anand Jain <anand.jain@oracle.com>
(This patch is for the review/test not yet for the integration).
Here is an implementation of the feature to add label to the
subvolume and snapshots. Which would help sysadmin to better manager
the subvol and snapshots.
This can be done in two ways, one - using attr which is user land
only changes but drawback is able to change the label
