* [PATCH] Use ZVC for free_pagesChristoph Lameter2007-02-11
| | | | | | | | | | | This is again simplifies some of the VM counter calculations through the use of the ZVC consolidated counters.

* [PATCH] BLOCK: Separate the bounce buffering code from the highmem code [try #6]David Howells2006-09-30
| | | | | | | | | | | Move the bounce buffer code from mm/highmem.c to mm/bounce.c so that it can be more easily disabled when the block layer is disabled. !!!NOTE!!! There may be a bug in this code: Should init_emergency_pool() be contingent on CONFIG_HIGHMEM? Signed-Off-By: David Howells <dhowells@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>

* [PATCH] zoned vm counters: conversion of nr_bounce to per zone counterChristoph Lameter2006-06-30
| | | | | | | | | | | | | | Conversion of nr_bounce to a per zone counter nr_bounce is only used for proc output. So it could be left as an event counter. However, the event counters may not be accurate and nr_bounce is categorizing types of pages in a zone. So we really need this to also be a per zone counter.

* BUG_ON() Conversion in mm/highmem.cEric Sesterhenn2006-04-02
| | | | | | | | this changes if() BUG(); constructs to BUG_ON() which is cleaner, contains unlikely() and can better optimized away. Signed-off-by: Eric Sesterhenn <snakebyte@gmx.de> Signed-off-by: Adrian Bunk <bunk@stusta.de>
* [PATCH] mempool: use common mempool page allocatorMatthew Dobson2006-03-26
| | | | | | | | | | | Convert two mempool users that currently use their own mempool-backed page allocators to use the generic mempool page allocator. Also included are 2 trivial whitespace fixes.

* [PATCH] gfp flags annotations - part 1Al Viro2005-10-08
| | | | | | | | | | | | - added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better.

* [PATCH] count bounce buffer pages in vmstatKAMEZAWA Hiroyuki2005-05-01
| | | | | | | | | | | | | | This is a patch for counting the number of pages for bounce buffers. It's shown in /proc/vmstat. Currently, the number of bounce pages are not counted anywhere. So, if there are many bounce pages, it seems that there are leaked pages. And it's difficult for a user to imagine the usage of bounce pages. So, it's meaningful to show # of bouce pages.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
