[PATCH] mm: __GFP_NOFAIL fix
In __alloc_pages():
if ((p->flags & (PF_MEMALLOC | PF_MEMDIE)) && !in_interrupt()) {
/* go through the zonelist yet again, ignoring mins */
for (i = 0; zones[i] != NULL; i++) {
struct zone *z = zones[i];
page = buffered_rmqueue(z, order, gfp_mask);
if (page) {
zone_statistics(zonelist, z);
goto got_pg;
}
}
goto nopage; <<<< HERE!!! FAIL...
}
kswapd (which has PF_MEMALLOC flag) can fail to allocate memory even when
it allocates it with __GFP_NOFAIL flag.
