[PATCH] msync: fix return value
msync() does a strange thing. Essentially:
vma = find_vma();
for ( ; ; ) {
if (!vma)
return -ENOMEM;
...
vma = vma->vm_next;
}
so an msync() request which starts within or before a valid VMA and which ends
within or beyond the final VMA will incorrectly return -ENOMEM.
Fix.
