Subject[PATCH 2/4] mm/hugeltb: simplify the return code of __vma_reservation_common()
Date
It's guaranteed that the vma is associated with a resv_map, i.e. either
VM_MAYSHARE or HPAGE_RESV_OWNER, when the code reaches here or we would
have returned via !resv check above. So ret must be less than 0 in the
'else' case. Simplify the return code to make this clear.
