[Zesty][PATCH 0/1] UBUNTU: SAUCE: Tools: hv: vss: Thaw the filesystem and continue after freeze fails

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1470250

== SRU Justification ==
Several Hyper-v users have reported running various versions of Ubuntu 
on Generation 2 Hyper-V Hosts. On a random Basis, the file system will be 
mounted Read-Only due to a "disk error" (which really isn't the case here). 
As a result, they must reboot the Ubuntu guest to get the file system to mount RW again.

This bug usually happens during the backup procedure and causes the backup to fail.

This bug is fixed by the following three commits:
497af84b81b9 Drivers: hv: utils: Continue to poll VSS channel after handling requests
b357fd3908c1 Drivers: hv: vss: Operation timeouts should match host expectation
Ubuntu: SAUCE: (no-up) Tools: hv: vss: Thaw the filesystem and continue after freeze fails

Zesty master-next already has the first two commits, so only the SAUCE patch is
needed.  The SAUCE patch has not been submitted upstream yet, but it will be
in the future.

Trusty, Yakkety and Xenial also need these fixes.  However, Trusty needs several
prereq commits and Y/Z need the first two commits mentioned above.  Becuase of this,
the will be SRU'd separately.

    Tools: hv: vss: Thaw the filesystem and continue after freeze fails


== Test Case ==
A test kernel was built with this patch and tested by several bug reporters.
The bug reporters state the test kernel resolved the bug.
