[SRU][Trusty][Yakkety][Xenial][PATCH 0/1] btrfs: fix btrfs_compat_ioctl failures on non-compat ioctls

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1619918

== SRU Justification ==
Commit 4c63c2454ef intended to fix the original issue reported in bug 1619918.  
However, it introduced a sedondary regression where sudo btrfs fi show" 
no longer works and only puts out "Btrfs v3.12".  It also prevented btrfs 
snapshots from working.  This new bug would only happen with 32 bit 
userspace and a 64 bit kernel.

Commit 2a362249 now fixes both bugs instread of having commit 4c63c2454ef
reverted. Commit 2a362249 was also cc'd to upstream stable.

== Fix ==
commit 2a362249187a8d0f6d942d6e1d763d150a296f47

    btrfs: fix btrfs_compat_ioctl failures on non-compat ioctls

== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
