      dm: path selector use module refcount directly · aea90588
      Jun'ichi Nomura authored
      Fix refcount corruption in dm-path-selector
      Refcounting with non-atomic ops under shared lock will corrupt the counter
      in multi-processor system and may trigger BUG_ON().
      Use module refcount.
      # same approach as dm-target-use-module-refcount-directly.patch here
      # https://www.redhat.com/archives/dm-devel/2008-December/msg00075.html

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      Let it rip!
