Subject: [PATCHv24 00/16] Contiguous Memory Allocator
Date: Tue, 03 Apr 2012 16:10:05 +0200
Message-ID: <1333462221-3987-1-git-send-email-m.szyprowski@samsung.com> (raw)

Hi,

This is (yet another) update of CMA patches. I've rebased them onto
recent v3.4-rc1 kernel tree and integrated some minor bugfixes. The
first issue has been pointed by Sandeep Patil - alloc_contig_range
reclaimed two times too many pages, second issue (possible mismatch
between pageblock size and MAX_ORDER pages) has been recently spotted
by Michal Nazarewicz.

These patches are also available on my git repository:
git://git.linaro.org/people/mszyprowski/linux-dma-mapping.git 3.4-rc1-cma-v24

Best regards
Marek Szyprowski

v24:
    1. fixed handling of diffrent sizes of pageblock and MAX_ORDER size
       pages

    2. fixed number of the reclaimed pages before performing the allocation
       (thanks to Sandeep Patil for pointing this issue)

    3. rebased onto Linux v3.4-rc1

v23:
    1. fixed bug spotted by Aaro Koskinen (incorrect check inside VM_BUG_ON)

    2. rebased onto next-20120222 tree from
       git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git 

v22:
    1. Fixed compilation break caused by missing fixup patch in v21

    2. Fixed typos in the comments

    3. Removed superfluous #include entries

v21:
    1. Fixed incorrect check which broke memory compaction code
