[PATCH v2 0/3] xfs_quota: allow operation on ext4 for project quotas

[Bill O'Donnell]

Hello -

I'm submitting a version 2 to clarify patch 1 loop logic correction.

This is a resubmission of Dave Chinner's original 2-patch series
to enable using xfs_quota for project quotas on foreign filesystems
(e.g. ext4).

Original series: http://oss.sgi.com/archives/xfs/2016-02/msg00107.html

Updated series:
Patch 1: initial capabilities to enable xfs_quota use on foreign filesystems.
Patch 2: userspace changes to accomodate hoisted ioctl defs in kernel
Patch 3: additional changes to accomodate xfs_quota use on foreign filesystems.

History:
-----
v1: http://oss.sgi.com/archives/xfs/2016-08/msg00435.html
v2: patch 1: slight logic modification to clarify loop in init_args_command
             (functional equivalent)

Again, questions and comments are welcome.

Thanks-
Bill
