[BUG] in do_mmap_pgoff() (2.4.19-preX)

Hi,

While documenting the do_mmap_pgoff() function, i found this
snippet of code very suspicious:

/* Private writable mapping? Check memory availability.. */
if ((vm_flags & (VM_SHARED | VM_WRITE)) == VM_WRITE &&
!(flags & MAP_NORESERVE) &&
!vm_enough_memory(len >> PAGE_SHIFT))
return -ENOMEM;

Here we need to quit if *any* one of the condition is true. So I
think it should be "||" instead of "&&". As according to the present
code, it quits only if all the 3 conditions is true, which is wrong.

Bye,
Abhi.
