This may happens because of direct write.
Please add exact fsstess command and options.

What i found was also related. The file which had errors had the below
operations on them.
82/901: dread d16/d20/d22/d2d/d63/d68/d9a/f93 [622592,53248] 0
82/939: dwrite d16/d20/d22/d2d/d63/d68/d9a/f93 [1093632,77824] 28
9/863: fallocate d1/d2d/d32/d8f/d97/d108/d9b/ffb [2041,75851] 28
18/733: fallocate d9/ddd/f86 [481025,18486] 0
18/735: dwrite d9/ddd/f86 [679936,36864] 0
18/764: dread d9/ddd/f86 [53248,8192] 0
18/910: dwrite d9/ddd/f86 [1454080,4096] 28
18/999: dwrite d9/ddd/f86 [1798144,61440] 28
But what would happen during direct write that cause this ?

Ohh it is long live bug in direct-io error handling logic:
http://lkml.org/lkml/2006/12/18/103
So IMHO it is beter to disable direct-io writes in your case.

Why is the patch not yet available in the Linus tree ? Does this mean
that i will not be able to test direct io write at all. Right
now i did
#ifdef ENOSPC_BUG_DIRECT_IO_YES
{ OP_DREAD, "dread", dread_f, 4, 0 },
{ OP_DWRITE, "dwrite", dwrite_f, 4, 1 },
#endif
i am not interested in dread, so commented that also.
fsstress ran successfully with this change.

Because not everybody was happy about this solution. I'll send new version
today.

Strictly saying YES, but practically you can use direct-io writes if
you have enough disk space.
