From 71cdb6978a80f9f6c51bef0622388c1414c2fe32 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 15 Oct 2015 14:10:51 +0200 Subject: dm: add support for passing through persistent reservations This adds support to pass through persistent reservation requests similar to the existing ioctl handling, and with the same limitations, e.g. devices may only have a single target attached. This is mostly intended for multipathing.
