Hi all,

working on arm (32bit arch), kernel 4.1.6.
Looking to find the reason of a bad result on xfstests,

-tests/generic/009
------------------
i get several "all holes" messages

also some other tests are giving the same bad notices.

-tests/generic/308
------------------

I have now: CONFIG_LBDAF=y

In my target device this test creates a 16 Terabytes file 308.tempfile

-rw------- 1 root root 17592186044415 Sep 18 09:40 testfile.308

While "df" is not complaining about:

/dev/mmcblk0p5 8378368 45252 8333116 1% /media/p5

and next rm -f on it hands the cpu to 95%, forever.

This issue seems known from a long time, as it has been discussed in the
thread:

http://oss.sgi.com/archives/xfs/2013-04/msg00273.html

I was wondering if there was any special reason why the Jeff patch has
never been finally applied.

I applied this patch anyway, and tests pass.
