Dave Chinner has pointed out this test is largely pointless:

   Perhaps one should question whether generic/125 is actually testing
   anything useful in the first place.

   i.e. it's writing 16k, then truncating it back to 1000 bytes, then
   reading it with direct IO for 60s to see if it returns the correct
   data for that entire time.

   What, exactly, is going to cause that test to fail?

   Keep in mind this was ported from a CXFS test, where the metadata
   server did the truncation operation (including the data zeroing),
   but the reads are being done from the client.  i.e. it was designed
   to test whether a remote machine is doing a truncate correctly on a
   access shared disk.

   IMO, I think we just remove the test, src/trunc.c and src/ftrunc.c
   because it's 60s of testing that doesn't actually provide any value
   to us.

The pNFS block layout driver works the same way as CXFS here.  I
don't think I ever triggered this test during the development, though.

I'm indifferent on whether we should keep this test or not, but it
defintively makes sense to remove it from the auto group.

Ok, if there's some value to using it for pNFS testing, then lets
leave it in place, remove the auto group but also add a "pnfs" group
tag to it to document what it's useful for.

Sorry to give you the run-around on this one, Ted. Can you resend
it?

Cheers,

Dave.

I think it might only be border line useful.  If you two feel better if
it's gone I'm fine with killing it.
