[LTP] [PATCH v2] syscalls/keyctl09: test encrypted keys.

[Petr Vorel]

Hi Yael,

you still have some problem when running more iterations:

./keyctl09 -i500
keyctl09.c:49: TPASS: Encrypted keys were successfully instantiated and read
keyctl09.c:49: TPASS: Encrypted keys were successfully instantiated and read
...
keyctl09.c:33: TFAIL: Failed to instantiate encrypted key using payload decrypted data

(some people really try high number of iterations.)
Could you please have a look?

+1 for doc!

nit: this might be TBROK (test preparation phase), not sure
(and not that important).

The rest LGTM.
