Crap you cannot do PAGE_SIZE allocations with kmalloc_large. Fails when freeing pages. Need to only do the multiple page allocs with kmalloc_large. Subject: seq_file: Use kmalloc_large for page sized allocation There is no point in using the slab allocation functions for large page order allocation. Use kmalloc_large(). This fixes the warning about large allocs but it will still cause large contiguous allocs that could fail because of memory fragmentation.
