Subject: [PATCH 0/7] blktrace: various cleanups and fixes
Date: Fri, 20 Mar 2009 09:47:05 +0800 [thread overview]
Message-ID: <49C2F599.3060306@cn.fujitsu.com> (raw)
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
