[LTP] [PATCH] kernel/syscalls/open14: openat03: add new test-cases
Alexey Kodanev
alexey.kodanev@oracle.com
Wed Jan 20 15:02:41 CET 2016
* create multiple directories and related temporary files;
* create multiple directories and link files into them. Check
that files permissions correspond to the ones specified with
open()/openat().
