| Doc Text: |
Prior to this update, multipathd did not always remove a path's sysfs device from cache when the path was removed. Also, multipathd searched the cache and created sysfs devices without the 'vecs' lock held. As a result, paths would occasionally have invalid sysfs devices, causing multipathd crashes and other errors. With this update, multipathd always removes the sysfs device from cache when deleting the path, and it only accesses the cache with the 'vecs' lock held.
