hugetlb: fix error return for brk() entering a hugepage region
The lats commit causes the wrong return value. is_hugepage_only_range() is a boolean, so we should return -EINVAL rather than 1. Also - we can use "mm" instead of looking up "current->mm" again. Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: Adrian Bunk <bunk@kernel.org>
