SubjectRe: [PATCH] net: Add back alignment for size for __alloc_skb

kmalloc() behavior doesn't have anything to do with this bug.

The issue is calculation of skb->end, which is based upon calculated
'size' variable.

skb->end determines alignment of skb_shared_info, which is where the
alignment problem is occuring for Tony.
