I disagree; xfstests is the right place for adding these tests, because
these patches seem to require fs-specific support, and file system
developers are already using xfstests when checking for regressions.
Using xfstests is already part of most of the file system developers'
workflow; ltp is not. 

So if you want to make sure we notice regressions, it really needs to
go into xfstests.  If you insist on putting it in ltp, then one of us
will then have to make a copy of the tests and put it in xfstests.

Cheers,
