I can send you the test-suite.log if you think it's important (but
don't want to clog up your inboxes unnecessarily if you don't). If it
makes any difference, I'm still using an ext2 filesystem (the test is
skipped on ext3); if that's the problem then perhaps just add to
tests/cp/fiemap-perf the lines:

df -t ext2 . >/dev/null &&
  skip_ "ext2 has known slow FIEMAP scanning"

(by analogy with the ext3 case which you already screen for)?

I'm not subscribed, so please to cc any replies to me.

               Yours,

That sounds right.
I'll apply that patch in your name after some testing.
Which email address would you prefer.

cheers,
Pádraig.

I suspect the actual failure was due to
not being able to create a 1T sparse file
on an ext2 file system with 1K block size.
So I'm going to push this...

    tests: fiemap-perf: avoid a false failure on ext2

    * tests/cp/fiemap-perf: Skip the test on ext2 file systems,
    as we do for ext3.  Also skip the test if we can't create
    a 1TiB file, which can happen on ext2 for example where
    the sparse file size limit is lower than that of ext4.
