Merge proc-self-map-files tests into one since this test should focus in testing readlink in /proc/self/map_files/* only, and not trying to test mapping virtual address 0.
Lowest virtual address for user space mapping in other architectures, like arm, is *at least* *(PAGE_SIZE * 2) and NULL hint does not guarantee that when MAP_FIXED flag, important to this test, is given. This patch also fixes this issue in remaining test.
- p = mmap(NULL, PAGE_SIZE, PROT_NONE, MAP_PRIVATE|MAP_FILE, fd, 0);
- p = mmap((void *) (2 * PAGE_SIZE), PAGE_SIZE, PROT_NONE,
I don't know ARM. Is this 2 page limitation a limitation of hardware or kernel's?
Ahh. please test the path I've sent, I don't have arm install readily available.
I replied to your patch based on some of the discussion we had in this thread.
Thanks
