Olaf Faaland 14c240cede Detect long config lock acquisition in mmp ... If something holds the config lock as a writer for too long, MMP will fail to issue MMP writes in a timely manner. This will result either in the pool being suspended, or in an extreme case, in the pool not being protected. If the time to acquire the config lock exceeds 1/10 of the minimum zfs_multihost_interval, report it in the zfs debug log.
