Subject[PATCH 00/15] Kernel memory leak detector
From
Date
A new kmemleak version is available. Thanks to all who reviewed the code
and gave feedback. Kmemleak can also be found on this git tree:

git://linux-arm.org/linux-2.6.git kmemleak

Please note that even though I already got the ack from the
slab/slob/slub maintainers, I haven't included the corresponding lines
in the patch description because the patches were slightly modified to
pass the GFP flags to the kmemleak callbacks. I would be grateful if you
review these changes and re-acknowledge them.

Changes since the previous release:

- fatal errors for kmemleak are no longer fatal for the full system.
Kmemleak can disable and clean-up after itself at run-time if such a
condition occurs
- re-worked locking in the memleak.c file together with documentation on
how it works
- kmemleak internal allocations use the GFP flags of the caller and are
no longer restricted to GFP_ATOMIC
- better (hopefully) comments all over the code
- implemented most of the comments received so far (an important
omission here is the tracking of alloc_bootmem calls since it looks a
bit difficult to pair them with free_bootmem, the latter being used
with reserve_bootmem or without a corresponding alloc_bootmem)

Still to do:

- run-time and boot-time configuration like task stacks scanning,
disabling kmemleak, enabling/disabling the automatic scanning

Thanks for your comments.
