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 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
