Subject: [PATCH] multipath: return failure on an invalid remove command
When "multipath -f" is run on a device that doesn't exist or isn't a
multipath device, the command will not remove any device, but it will
still return success. Multiple functions rely on _dm_flush_map()
returning success when called with name that doesn't match any
multipath device. So before calling _dm_flush_map(), call dm_is_mpath(),
to check if the device exists and is a multipath device, and return
failure if it's not.

Subject: [PATCH] libmultipath: steal the src string pointer in merge_str()
Instead of allocating a copy when the original string is going to be
freed right after the merge, just steal the pointer. Also, merge_mpe()
can't get called with NULL arguments.

Subject: [PATCH] libmultipath: enable linear ordering of bus/proto tuple
We categorized protocols by bus/proto_id, while we only differentiate
protocol IDs for SCSI. Allow transforming this into a linear sequence
of bus/protocol IDs by having non-SCSI first, and follwing up with
the different SCSI protocols.

Subject: [PATCH] libmultipath: add a protocol subsection to multipath.conf
Some storage arrays can be accessed using multiple protocols at the same
time. In these cases, users may want to set path attributes
differently, depending on the protocol that the path is using. To allow
this, add a protocol subsection to the overrides section in
multipath.conf, which allows select path-specific options to be set.
This commit simply adds the subsection, and handles merging matching
entries. Future patches will make use of the section.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Benjamin Marzinski <bmarzins@redhat.com>
Date: Wed, 13 Apr 2022 23:27:38 -0500
Subject: [PATCH] libmultipath: Set the scsi timeout parameters by path
Instead of dev_loss, fast_io_fail, and eh_deadline belonging to the
multipath structure, have them belong to the path structure. This means
that they are selected per path, and that sysfs_set_scsi_tmo() doesn't
assume that all paths of a multipath device will have the same value.
Currently they will all be the same, but a future patch will make it
possible for paths to have different values based on their protocol.

Subject: [PATCH] libmultipath: check the overrides pctable for path variables
Paths will now also check the pctable when checking for attribtes that
exists in both the overrides section and the protocol subsection. Values
in a matching pcentry will be used in preference to values in the
overrides hwentry.
