No worries, Chandra.  I couldn't even get the echo line for Eric's 
patched version and execute the script in the same pass.  There's 
something about debugging the passing of arguments in bash that is 
simply evil.

Oh, so leave it to me to hack my lone swap partition on this PC into a 
two-segment dm-linear device so I can test this...OK...that was 
successful for a change!  Even though `git am` complained about the 
whitespace (E-mail issue?), the patch worked as well.

Anyway, there are issues with these tests and whether the partitions are 
mounted at the time ./check is run, but that will be posted after my 
closing, just to put it out there that issues may exist in the mount 
checking.  [And I'm sure that I did an `export USE_EXTERNAL="yes"`, so 
it's surprising how the tests went about mounting.]

=====================================================================
This is how things went before using Eric's patch:

root@plbearer:/var/lib/xfstests# ./check generic/001
mount: wrong fs type, bad option, bad superblock on /dev/mapper/tData,
        missing codepage or helper program, or other error
        In some cases useful info is found in syslog - try
        dmesg | tail  or so

Anyway, thanks for the patch!  It will put me back on track.  This 
xfstests restructuring looks like a significant undertaking, and issues 
along the way are expected.

Good luck!

P.S. - This is what three passes in a row looks like, using Eric's 
patched version of ./check:
