Fair enough.

Well you free() later in the function. But Cyril's  note sounds reasonable for
me:
	"call it once in the test setup() or use "." instead."

Could you please do it?

Also most of the tests really run tst_get_tmpdir() in the setup() (or cleanup(),
there are exceptions (new API: testcases/kernel/syscalls/pathconf/pathconf01.c,
old API: testcases/kernel/syscalls/symlink/symlink01.c,
testcases/kernel/syscalls/clone/clone02.c), which should be fixed.
IMHO tests which call tst_get_tmpdir() in the run()

Kind regards,
Petr
