pai ...
# cd /usr/src/kernel-2.4.10
# vim mm/page_alloc.c
/__alloc_pages --> linia 316
/*
* This is the 'heart' of the zoned buddy allocator:
*/
struct page * __alloc_pages(unsigned int gfp_mask, unsigned int order,
zonelist_t *zonelist)
{
[...]
... vezi si tu ce face functia asta ... probabil aloca pagini in memoria
virtuala ...
... si undev, pe la sfarsitul functiei e un
printk(KERN_NOTICE "__alloc_pages: %u-order allocation failed (gfp=0x%x/%i) from
%p\n",
order, gfp_mask, !!(current->flags & PF_MEMALLOC),
__builtin_return_address(0));
return NULL;
deci se pare ca nu i`a reusit alocarea dupa toate variantele incercate
mai sus ...
dar sincer nu stiu exact ce semnific au parametrii aceia ... daca ai
timp sa studiezi problema zi`ne si noua pe lista :)
