Nick Piggin	b84a35be02	[PATCH] mempool: NOMEMALLOC and NORETRY ... Mempools have 2 problems. The first is that mempool_alloc can possibly get stuck in __alloc_pages when they should opt to fail, and take an element from their reserved pool. The second is that it will happily eat emergency PF_MEMALLOC reserves instead of going to their reserved pools. Fix the first by passing __GFP_NORETRY in the allocation calls in mempool_alloc. Fix the second by introducing a __GFP_MEMPOOL flag which directs the page allocator not to allocate from the reserve pool.

Nick Piggin	8e30f272a9	[PATCH] mm: pcp use non powers of 2 for batch size ... Jack Steiner reported this to have fixed his problem (bad colouring): "The patches fix both problems that I found - bad coloring & excessive pages in pagesets." In most workloads this is not likely to be such a pronounced problem, however it should help corner cases. And avoiding powers of 2 in these types of memory operations is always a good idea.

Linus Torvalds	1da177e4c3	Linux-2.6.12-rc2 ... Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!	2005-04-16 15:20:36 -07:00
