This patchset is a combination of my previous two patchsets
[PATCH 0/5] multipath: Add a group_by_tgp path grouping policy
[PATCH 0/5] priority and pathgroup switching changes
The first part adds a new path grouping policy that can be used with
ALUA devices. The goal is to avoid the temporary incorrect path
groupings that can happen when paths change priorities.
The second part is changes that mostly effect how multipathd handles
switching or reordering pathgroups for devices where group_by_prio isn't
set.
Differences from V1 (from changes suggested by Martin Wilck):
[05/11]: make detect_pgpolicy set group_by_prio instead of group_by_tpg
[06/11]: New patch. Add detect_pgpolicy_use_tpg to pick group_by_tpg
instead of group_by_prio
[09/11]: Large rewrite of my "multipathd: refresh all priorities if one
has changed" patch based on discussions with Martin
[10/11]: This just moves path_groups_in_order() to multiapthd, and adds
a comment explaining why it works different from
select_path_group().
Benjamin Marzinski (11):
libmultipath: add group_by_tpg path_grouping_policy
libmultipath: don't copy pgpolicy string in get_pgpolicy_name
libmultipath: add ALUA tpg path wildcard
multipath-tools tests: add tests for group_by_tpg policy
libmultipath: add "detect_pgpolicy" config option
libmultipath: add "detect_pgpolicy_use_tpg" config option
libmultipath: don't count PRIO_UNDEF paths for pathgroup priority
multipath-tools tests: add tests to verify PRIO_UDEF changes
multipathd: only refresh priorities in update_prio()
multipathd: reload map if the path groups are out of order
multipathd: don't assume mpp->paths will exist in
need_switch_pathgroup
