-From: Kiyoshi Ueda <k-ueda@ct.jp.nec.com>
-Subject: dm-mpath: add a path selector interface
-References: FATE#303862,FATE#302108
-
-This patch adds a new hook for dm path selector: start_io.
-Target drivers should call this hook before submitting I/O to
-the selected path.
-Path selectors can use it to start accounting of the I/O.
-(e.g. counting the number of in-flight I/Os.)
-
-The code is based on the patch posted by Stefan Bader:
-https://www.redhat.com/archives/dm-devel/2005-October/msg00050.html
