https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-2.6.21.y2007-02-11T18:51:18Z[PATCH] optional ZONE_DMA: optional ZONE_DMA in the VM2007-02-11T18:51:18ZChristoph Lameter2007-02-10T09:43:10Zurn:sha1:4b51d66989218aad731a721b5b28c79bf5388c09
Make ZONE_DMA optional in core code.
- ifdef all code for ZONE_DMA and related definitions following the example
for ZONE_DMA32 and ZONE_HIGHMEM.
- Without ZONE_DMA, ZONE_HIGHMEM and ZONE_DMA32 we get to a ZONES_SHIFT of
0.
- Modify the VM statistics to work correctly without a DMA zone.
- Modify slab to not create DMA slabs if there is no ZONE_DMA.

[PATCH] Cleanup slab headers / API to allow easy addition of new slab allocators2006-12-13T17:05:49ZChristoph Lameter2006-12-13T08:34:23Zurn:sha1:2e892f43ccb602e8ffad73396a1000f2040c9e0b
This is a response to an earlier discussion on linux-mm about splitting
slab.h components per allocator. Patch is against 2.6.19-git11. See
http://marc.theaimsgroup.com/?l=linux-mm&m=116469577431008&w=2
This patch cleans up the slab header definitions. We define the common
functions of slob and slab in slab.h and put the extra definitions needed
for slab's kmalloc implementations in <linux/slab_def.h>. In order to get
a greater set of common functions we add several empty functions to slob.c
and also rename slob's kmalloc to __kmalloc.
Slob does not need any special definitions since we introduce a fallback
case. If there is no need for a slab implementation to provide its own
kmalloc mess^H^H^Hacros then we simply fall back to __kmalloc functions.
That is sufficient for SLOB.
Sort the function in slab.h according to their functionality. First the
functions operating on struct kmem_cache * then the kmalloc related
functions followed by special debug and fallback definitions.
Also redo a lot of comments.
