[LTP] [PATCH 1/1] keyctl05: Add modprobe dns_resolver

[Petr Vorel]

This avoids TCONF when module not loaded:
keyctl05.c:99: TCONF: kernel doesn't support key type 'dns_resolver'

There is no way to trigger module loading automatically.

Hi,

a candidate to merge before release (simple enough).

I'll try to send a patchset for .modprobe_module before the release, but
I suppose we should merge it after the release anyway. That's why I
added this simple patch. And therefore I don't bother with 'modprobe -r',
neither with requiring modprobe (will be in .modprobe_module).

Kind regards,
Petr
