[LTP] [PATCH 12/13] Hugetlb: Migrating libhugetlbfs shm-fork

[Petr Vorel]

Hi,

> Migrating the libhugetlbfs/testcases/shm-fork.c test
NOTE: if you're talking about libhugetlbfs [1], the test path is
tests/shm-fork.c (not testcases).


> Test Description: Test shared memory behavior when multiple threads are
> Test shared memory behavior when multiple threads are attached
> to a segment.  A segment is created and then children are
> spawned which attach, write, read (verify), and detach from the
> shared memory segment.

You're not define tst_option [2] (you don't even have any code which would hold
these options), therefore passing any of these 2 options will quit the test:
hugefork02: invalid option -- 'P'

Please fix it in next version.

Kind regards,
Petr
