Message-ID: <49C2F599.3060306@cn.fujitsu.com> Date: Fri, 20 Mar 2009 09:47:05 +0800 From: Li Zefan <lizf@...fujitsu.com> To: Ingo Molnar <mingo@...e.hu> CC: Jens Axboe <jens.axboe@...cle.com>, Arnaldo Carvalho de Melo <acme@...hat.com>, Steven Rostedt <rostedt@...dmis.org>, Frederic Weisbecker <fweisbec@...il.com>, LKML <linux-kernel@...r.kernel.org> Subject: [PATCH 0/7] blktrace: various cleanups and fixes While trying to use blktrace in -tip tree, I encounted kernel NULL dereference, so I looked into the code, and then found some other bugs. This patchset is part 1, and I have some other pending fixes. Each patch is small and straightforward, and should be easy to review: [PATCH 1/7] blktrace: fix possible memory leak [PATCH 2/7] blktrace: make blk_tracer_enabled a bool flag [PATCH 3/7] blktrace: remove blk_probe_mutex [PATCH 4/7] blktrace: don't increase blk_probes_ref if failed to setup blk trace [PATCH 5/7] blktrace: report EBUSY correctly [PATCH 6/7] blktrace: remove sysfs_blk_trace_enable_show/store() [PATCH 7/7] blktrace: avoid accessing NULL bdev->bd_disk --- blktrace.c | 154 +++++++++++++++++-------------------------------------------- 1 file changed, 45 insertions(+), 109 deletions(-) Signed-off-by: Li Zefan <lizf@...fujitsu.com> -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
