Hi!
I've found another problem while doing pre-release testing.
The keyctl03 and sometimes keyctl05 fails with EDQUOT when executed
right after keyctl02 which creates and revokes keys in the loop and also
adjusts the quota temporarily. It fails for me on kernel 3.16 inside of
a qemu virtual machine. Looks like the keys are not deleted after the
keyctl02 test exits. Have anybody seen a failure like this one?

I tested on RHEL7.4GA(Kernel 3.10.0-693.el7.x86_64) in my virtual
machine and physical machine, keyctl03 right after keyctl02 or
keyctl05 right after keyctl02, both worked well.
On mainline kernel 3.16, keyctl02 and keyctl03 triggered the bug
and crashed the system.

I've managed to reproduce it on 3.12 as well. The problem is visible on
SLES12 SP1 as well as Debian 8.8.

You have to have the patch that fixes the kernel crash backported
obviously, which happens mostly for distribution maintained kernels.
The question is if we care enough about these failures to do something
about them before the release. I guess that we do not.
