[LTP] [PATCH] lib: TST_EXP_FAIL: Add array variants

[Petr Vorel]

Hi Cyril,

I suppose this patchset is a preparation for splice07, right?

https://lore.kernel.org/ltp/20231024093320.wsusd5qtveqt64dt@quack3/

Hopefully we could merge this and tst_fd iterator API before the release.

Kind regards,
Petr
