From 48105f492f7f8c157ba714217ae55c6fb50e76c0 Mon Sep 17 00:00:00 2001
From: Maxim Plotnikov <wgh@torlan.ru>
Date: Wed, 22 Apr 2020 00:16:29 +0300
Subject: [PATCH] Fix scripts/lvmlocks.service.in using nonexistent --lock-opt
autowait
The --lock-opt autowait was dropped back in 9ab6bdce01,
and attempting to specify it has quite an opposite effect:
no waiting is done, which makes the unit almost useless.

+The block size to use for dm-integrity on raid images.

+Use a journal (default) or bitmap for keeping integrity checksums consistent
+in case of a crash. The bitmap areas are recalculated after a crash, so corruption
+in those areas would not be detected. A journal does not have this problem.
+The journal mode doubles writes to storage, but can improve performance for
+scattered writes packed into a single journal write.
+bitmap mode can in theory achieve full write throughput of the device,
+but would not benefit from the potential scattered write optimization.

+ Check if lvcreate passes read_only_volume_list with tags and skips zeroing.
+ Limit pool metadata spare to 16GiB.
+ Improves conversion and allocation of pool metadata.
+ Support thin pool metadata 15.88GiB, adds 64MiB, thin_pool_crop_metadata=0.
Fix problem with wiping of converted LVs.
Fix memleak in scanning (2.03.11).
Fix corner case allocation for thin-pools.
