[dm-devel] [PATCH v3 0/1] Multipath io_err_stat fixes

[Benjamin Marzinski]

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.

Changes from v2:

0001: This is patch 0006 from v2. It is exactly the same code. But the
commit message now mentions that check_path() no longer switches paths
from delayed to pending.

Changes from v1:

0002: use cleanup_mutex instead of cleanup_unlock as suggested by
Martin

0003: add pthread_testcancel and use cleanup_mutex instead of
cleanup_unlock as suggested by Martin. Also, make tmp_pathvec a constant
pointer, since it should always equal _pathvec.

0004-0006 are new patches to deal with io_err_stat issues from Martin's
review
