page-types.c: fix name of unpoison interface

2010-10-07T07:41:24+00:00

The page-types utility still uses an out of date name for the
unpoison interface: debugfs:hwpoison/renew-pfn
This patch renames and fixes it.

numa: update Documentation/vm/numa, add memoryless node info

2010-05-27T16:12:57+00:00

Kamezawa Hiroyuki requested documentation for the numa_mem_id() and slab
related changes.  He suggested Documentation/vm/numa for this
documentation.  Looking at this file, it seems to me to be hopelessly out
of date relative to current Linux NUMA support.  At the risk of going down
a rathole, I have made an attempt to rewrite the doc at a slightly higher
level [I think] and provide pointers to other in-tree documents and
out-of-tree man pages that cover the details.

Let the games begin.

Documentation/vm: use better value for MAP_HUGETLB

2010-05-24T14:30:56+00:00

documentation: slightly more correct value for MAP_HUGETLB in map_hugetlb.c

still not correct for alpha, mips, parisc or xtensa but working out of
the box in the most common architectures without having to deal with
complicated macros or including architecture specific headers.

Documentation/vm/: split txt and source files

2010-03-12T23:52:35+00:00

Documentation/vm/:
Expose example and tool source files in the Documentation/ directory in
their own files instead of being buried (almost hidden) in readme/txt files.
This should help to prevent bitrot.

This will make them more visible/usable to users who may need
to use them, to developers who may need to test with them, and
to anyone who would fix/update them if they were more visible.

Also, if any of these possibly should not be in the kernel tree at
all, it will be clearer that they are here and we can discuss if
they should be removed.

Also build the recently-added map_hugetlb.c.
Make several functions static to prevent linker warnings.

failslab: add ability to filter slab caches

2010-02-26T17:19:39+00:00

This patch allow to inject faults only for specific slabs.
In order to preserve default behavior cache filter is off by
default (all caches are faulty).

One may define specific set of slabs like this:
# mark skbuff_head_cache as faulty
echo 1 > /sys/kernel/slab/skbuff_head_cache/failslab
# Turn on cache filter (off by default)
echo 1 > /sys/kernel/debug/failslab/cache-filter
# Turn on fault injection
echo 1 > /sys/kernel/debug/failslab/times
echo 1 > /sys/kernel/debug/failslab/probability
