Subject: [PATCH] [multipathd] add "show status" cli command
For now just print the number of paths in each path checker state,
if not zero. For example :
path checker states:
up 2
down 1
ghost 1

Subject: [PATCH] [multipathd] add "show wildcards" cli command
The fact I had to look at the code to find the wildcards to use
in "show paths format ...", "show multipath format ..." and
"show pathgroup format ..." was a clear sign that more help was
necessary.
The "show wildcards" command outputs :
multipath format wildcards:
%n name
%w uuid
%d sysfs
%F failback
%Q queueing
%N paths
%r write_prot
%t dm-st
%S size
%f features
%h hwhandler
%A action
%0 path_faults
%1 switch_grp
%2 map_loads
%3 total_q_time
%4 q_timeouts
%s vend/prod/rev
path format wildcards:
%w uuid
%i hcil
%d dev
%D dev_t
%t dm_st
%T chk_st
%s vend/prod/rev
%C next_check
%p pri
%S size
pathgroup format wildcards:
%s selector
%p pri
%t dm_st
And for example, "show paths format foo:%d:%S:%i", outs
foo:dev:size:hcil
foo:sda:149G:2:0:0:0

Git: 9ac06d484adb369c1848f5793cf36ab681899ef7
The mkinitrd boot script still tries to include the obsolete
device-mapper hardware handler modules. Update it to include
the SCSI device-handler modules.

Subject: [PATCH] [lib] Increase bindings file lock timeout to avoid failure of user_friendly_names
On setups with a large number of paths / multipath maps, contention for
the advisory lock on the bindings file may take longer than 3 seconds,
and some multipath processes may create maps based on WWID despite having
user_friendly_names set. Increasing the timeout is a simple fix that
gets us a bit further.
