Patch 1-3 of this series are a v2 of my previous series "multipath-tools:
udev rules and service improvements" posted on Feb 5th.
Changes wrt v1:
1/6: fix logic as pointed out by Ben Marzinski
2/6: Keep importing MPATH_DEVICE_READY as suggested by Ben Marzinski.
Don't import DM_UDEV_DISABLE_OTHER_RULES_FLAG any more.
Patch 4-6 are new. 4/6 implements new logic for setting
DM_UDEV_DISABLE_OTHER_RULES_FLAG_OLD, as discussed in the thread about 1/6
of the v1 series. 5/6 fixes a variant of the race condition that 3/6
addresses. Meanwhile I got positive test feedback about these patches; the
partner isn't observing any more errors with these patches applied. Thus
while certain types of race conditions (reload happening between
DM_SUSPENDED test in 10-dm.rules and blkid or pvscan calls in later rules)
are still possible, they seem to be rare enough to be handled in a separate
patch set.
6/6 is an unrelated new patch which is necessary to make CI for arm/v7
environments work.
Martin Wilck (6):
11-dm-mpath.rules: use import logic like 13-dm-disk.rules
11-dm-mpath.rules: don't import properties that are already set
11-dm-mpath.rules: handle reloads during coldplug events
11-dm-mpath.rules: don't save DM_UDEV_DISABLE_OTHER_RULES_FLAG_OLD
11-dm-mpath.rules: clear DM_DISABLE_OTHER_RULES_FLAG for coldplug
events
multipath-tools: Makefile.inc: set _FILE_OFFSET_BITS=64
