[PATCH] fs/xfs: Remove dead CONFIG_XFS_DMAPI
CONFIG_XFS_DMAPI doesn't exist in Kconfig and is never defined anywhere else, therefore removing all references for it from the source code. Because XFS_DMAPI is never defined, XFS_DMAPI_STRING is always an empty string. So we can remove all references to it. Signed-off-by: Christian Dietrich <qy03fugy(a)stud.infor... 21 Jul 2010 09:08
Kernel bisect: a query regarding commit identifiers
Hello All, Just a quick question. I'm going to do kernel bisect and was wondering if there are commit identifiers for the rc-GIT versions ? Or maybe I won't need it and could just do it like this: git-bisect bad 2.6.35-rc2-git3 git-bisect good 2.6.35-rc2-git4 ? Identifiers for rc versions appear in changelog... 22 Jul 2010 00:34
[RFC][PATCH 2/2][memcg] use virt-array for memcg.
This makes memcg to depend on CONFIG_MMU. == From: KAMEZAWA Hiroyuki <kamezawa.hiroyu(a)> Using virt_array for memcg's node information. Now, memcg allocates an array of pointer in the lengh of MAXNUMNODES to hold pointers for per-node information. This has 2 bad points - struct mem_cgroup can ... 21 Jul 2010 08:03
[RFC][PATCH 1/2][memcg] moving memcg's node info array to virtually contiguous array
These are just a _toy_ level patches yet. My final purpose is to use indexed array for mem_cgroup itself, it has IDs. Background: memory cgroup uses struct page_cgroup for tracking all used pages. It's defined as == struct page_cgroup { unsigned long flags; struct mem_cgroup *mem_cgroup; ... 21 Jul 2010 08:03
[PATCH] fix return value for mb_cache_shrink_fn when nr_to_scan > 0
Sorry. regerated the patch, please check it. I wrapped most code in single pair of spinlock ops for 2 reasons: 1) get spinlock 2 times seems time consuming 2) use single pair of spinlock ops can keep "count" consistent for the shrink operation. 2 pairs may get some new ces created by other processes. ... 21 Jul 2010 08:03

[PATCHv2 04/11] writeback: do not lose wake-ups in the forker thread - 2
From: Artem Bityutskiy <Artem.Bityutskiy(a)> Currently, if someone submits jobs for the default bdi, we can lose wake-up events. E.g., this can happen if 'bdi_queue_work()' is called when 'bdi_forker_thread()' is executing code after 'wb_do_writeback(me, 0)', but before 'set_current_state(TASK_INTERRUPTIBL... 21 Jul 2010 05:54
[PATCHv2 08/11] writeback: move last_active to bdi
From: Artem Bityutskiy <Artem.Bityutskiy(a)> Currently bdi threads use local variable 'last_active' which stores last time when the bdi thread did some useful work. Move this local variable to 'struct bdi_writeback'. This is just a preparation for the further patches which will make the forker thread decid... 21 Jul 2010 05:54
