When the checker thread enqueues paths for the io_err_stat thread to
check, it calls enqueue_io_err_stat_by_path() with the vecs lock held.
start_io_err_stat_thread() is also called with the vecs lock held.
These two functions both lock io_err_pathvec_lock. When the io_err_stat
thread updates the p
The checker thread is reponsible for enqueueing paths for the
io_err_stat thread to check. During shutdown, the io_err_stat thread is
shut down and cleaned up before the checker thread. There is no code
to make sure that the checker thread isn't accessing the io_err_stat
pathvec or its mutex while
I found an ABBA deadlock in the io_err_stat marginal path code, and in
the process of fixing it, noticed a potential crash on shutdown. This
patchset addresses both of the issues.

Actually I'm thinking why the first RFC version [1] I implemented can't
work.
Indeed iterating all hw queues of all target devices may not work well
as for performance. Then since we have an array of struct blk_mq_hw_ctx
* in struct dm_table now, we can also maintain a bitmap or something to
track

Add two helper macros calculating the offset of bio in struct dm_io and
struct dm_target_io respectively.
Besides, simplify the front padding calculation in
dm_alloc_md_mempools().
