Currently, we free the avc objects with holding a lock. To minimize

with holding a lock. Then, iterate them and free objects without holding

Improve the usage of return value 'result', so not only can make code
clearer to readers, but also can improve the performance.
Assign the return error code only when error occurs, so can save some
instructions (some of them are inside looping).
Rewrite the sysctl_getname() to make code clearer

Hi
We have a bug report when system fail to boot on 3.10 . It happens due to
problem in mei which do endless calls:
mei_reset -> mei_hbm_start_req -> mei_reset -> mei_hbm_start_req -> ...
It did not happen on 3.9.
Report is here:

Please see the previous commit which converts the subsystem methods

Reclaim zbud pages during migration and compaction by unusing stored

pages and effectively CMA pool can be used for zswap.

Hi,
Currently zbud pages are not movable and they cannot be allocated from CMA
region. These patches try to address the problem by:
1. Adding a new form of reclaim of zbud pages.
2. Reclaiming zbud pages during migration and compaction.
3. Allocating zbud pages with __GFP_RECLAIMABLE flag.

Move out the code for unusing swap entries from loop in try_to_unuse()
to separate function: try_to_unuse_swp_entry(). Export this new function
in swapfile.h just like try_to_unuse() is exported.

Use page reference counter for zbud pages. The ref counter replaces
zbud_header.under_reclaim flag and ensures that zbud page won't be freed
when zbud_free() is called during reclaim. It allows implementation of
additional reclaim paths.
The page count is incremented when:

Hi all,
Changes since 20130805:
The ext4 tree still has its build failure so I used the version from
next-20130726.
The akpm tree gained a conflict against the drm-intel tree.
I have created today's linux-next tree
Hi Johannes,
Thk for the cleanup.

Thanks for your contribution and sorry for taking so long to look at it.
While in principle I have no problem with these changes.
I would like them to be be accompanied by more descriptive
