Something noticed when studying use of VM_RESERVED in different drivers: snd_usX2Y_hwdep_pcm_vm_nopage omitted to get_page: fixed. And how did this work before? Aargh! That nopage is returning a page from within a buffer allocated by snd_malloc_pages, which allocates a high-order page, then does SetPageReserved on each 0-order page within. That would have worked in 2.6.14, because when the area was unmapped, PageReserved inhibited put_page. 2.6.15-rc1 removed that inhibition (while leaving ineffective PageReserveds around for now), but it hasn't caused trouble because.. we've not been freeing from VM_RESERVED at all.
