I was aware of that
please note that the allocation is independently for each block (and my
block size is 4Kbytes, an order 0 allocation):
for (i=0; i<req->tp_block_nr; i++) {
struct page *page, *pend;
pg_vec[i] = __get_free_pages(GFP_KERNEL, order);
if (!pg_vec[i])
goto out_free_pgvec;
pend = virt_to_page(pg_vec[i] + (PAGE_SIZE << order) - 1);
for (page = virt_to_page(pg_vec[i]); page <= pend; page++)
SetPageReserved(page);
}
I belive you get confused

no, I'm using 11, wich is the default in a 2.6.1 vanilla
Thanks again
