[LTP] [PATCH v8 0/7] Run tests in CI

[Petr Vorel <pvorel@suse.cz>]

Hi,

* print more items in lib into stderr (Cyril, 1st commit)
* check for readonly fs instead TCONF on any error during writing to
/proc/sys/vm/nr_hugepages (Cyril, 2nd commit)

NOTE: sending just these 2 patches which are different

Tested:
