(This affects only cluster locking because only cluster
locking module set LCK_PRE_MEMLOCK.)
With currect code you get
# vgchange -a n
Internal error: _memlock_count has dropped below 0.
when using cluster locking.
It is caused by _unlock_memory calls here
if ((flags & (LCK_SCOPE_MASK | LCK_TYPE_MASK)) == LCK_LV_RESUME)
memlock_dec();
Unfortunately it is also (wrongly) called in immediate unlock
(when LCK_HOLD is not set) from lock_vol
(LCK_UNLOCK is misinterpreted as LCK_LV_RESUME).
Avoid this by comparing original flags and provide memlock
code type of operation (suspend/resume).
All hidden (not visible) volumes should be activated through
other visible volumes.
(There are already exceptions like snapshot, mirror log and image,
which should be cleaned one day...)
This solves problems for future types of hidden volumes,
which can have special meaning and must not be activated implicitly
(e.g. key store volume).
This provides better support for environments where udev rules are installed
but udev_sync is not compiled in (however, using udev_sync is highly
recommended). It also provides consistent and expected functionality even
when '--noudevsync' option is used.
There is still requirement for kernel >= 2.6.31 for the flags to work though
(it uses DM cookies to pass the flags into the kernel and set them in udev
event environment that we can read in udev rules).
'last_rule' option has been removed from udev (version >= 147).
From now on, we require foreign rules to check and honor
ENV{DM_UDEV_DISABLE_OTHER_RULES_FLAG} instead. Foreign
rules should be skipped totally when this flag is set.

indented metadata lines.
Macro outnl() is using exported out_newline() instead of direct
call f->fn(), that required the visibility of the internal
struct formatter.
Rename fill_default_pvcreate_params to pvcreate_params_set_defaults.
Rename pvcreate_validate_restore_params to pvcreate_restore_params_validate.
Rename pvcreate_validate_params to pvcreate_params_validate.
- add copyright notice for 10-dm.rules.in,
- set DM_UDEV_DISABLE_{DISK, OTHER}_RULES_FLAG in 11-dm-lvm.rules directly
for inappropriate and non-top-level subdevices in case we use older kernels
where DM_COOKIE is not used (and therefore there are no flags passed from
the LVM process itself). This applies for older kernels (version < 2.6.31),
- remove unnecessary filters in 95-dm-notify.rules - the DM_COOKIE env var
itself is set for change/remove udev events and for DM devices only so
there's no need to double-check this.
Similar to other vg_set_* functions, we create a vg_set_clustered() function
which does a few checks and sets a flag. This is where we check for
any limitations of clusters.
The DRBD uses underlying device so code should prefer top
device if duplicate is found.
Patch also introduce
dev_subsystem_part_major and dev_subsytem_name
functions to easily handle all these replication susbystems
and not hardcode md_major call.

for full problem description.
Option --all is only partially documented currently, so document in all
commands. Also make {pv|vg|lv}{display|s} man pages consistent with help
output. Remove ununsed 'disk_ARG' parameter. Leave --trustcache out of
the man page output. Update --units argument to show all possible units.
