[LTP] [PATCH 1/2] lib: Add checking of needs_root

[Petr Vorel]

FYI I asked about the number of tests which need needs_rootgroup.
https://lore.kernel.org/ltp/Y0fAgGH6R8uEbcqh@pevik/

I thought these tests are somehow special (use root GID).
But if needs_rootgroup was meant for mount_device and needs_device I don't get
the point why (needs_root would be enough, but as Tim wrote that might be strict
for some people, thus we'd need the cyril's solution mentioned at
https://lore.kernel.org/ltp/Yx8I0ponDUIFC8le@yuki/

Or am I missing something obvious?

Kind regards,
Petr
