Using LLONG_MAX as maximum can fail on XFS, because here the maximum
file size is 2^63-1, so this test may unexpectedly succeed.
Impose limit via setrlimit(RLIMIT_FSIZE,..) and set value used
in EFBIG test to be twice that much.

I've found this failure on ext3 on SLES as well and tested that the
patch fixes the problem.

We have SAFE_SETRLIMIT() but that is merely cometic change.
Otherwise it's acked and tested, and as it fixes testcase regression it
should go in before the release.

Hello,
I find that EFBIG test will fail over nfs filesystem because
unexpectedly succeed too.
It can catch SIGXFSZ signal but will not fail with EFBIG after blocked
SIGXFSZ.
I'm not sure if it is expected behavior for truncate against nfs filesystem.
Could anyone help to check?
Thanks
Shuang

I'm guessing a bug. write(2) on nfs respects RLIMIT_FSIZE, but truncate(2) does not.
I think best would be to check with some nfs people: linux-nfs@vger.kernel.org
