Currently, if a hugetlbfs is mounted without limits (the default), statfs()
will return -1 for max/free/used blocks. This does not appear to be in
line with normal convention: simple_statfs() and shmem_statfs() both return
0 in similar cases. Worse, it confuses the translation logic in
put_compat_statfs(), causing it to return -EOVERFLOW on such a mount.
This patch alters hugetlbfs_statfs() to return 0 for max/free/used blocks
on a mount without limits. Note that we need the test in the patch below,
rather than just using 0 in the sbinfo structure, because the -1 marked in
the free blocks field is used internally to tell the
