[PATCH 21/40] generic/127: reduce runtime

[Dave Chinner <david@xxxxxxxxxxxxx>]

From: Dave Chinner <dchinner@xxxxxxxxxx>

...
generic/127 684
...

This takes a long time to run because it runs 6 individual
invocations of fsx sequentially. Make them run concurrently
as they can operate on separate files.

...
generic/127 168
