    [PATCH] msync: fix return value · 676758bd
    Andrew Morton authored
    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.
