Subject: [PATCH] fix return value after hugetlb mmap failure
Date: Mon, 30 Jun 2003 11:01:16 +1000	[thread overview]
Message-ID: <20030630010116.GA1784@krispykreme> (raw)


Hi,

At the moment no one uses is_aligned_hugepage_range or is_hugepage_only_range,
but it is reasonable to assume they return true or false. 

On error we want to return -EINVAL back to userspace.

Anton
