+Date: Fri, 8 Oct 2021 16:32:27 +0100
+Subject: [PATCH] arcstat: Fix integer division with python3
+
+The arcstat script requests compatibility with python2 and python3, but
+PEP 238 modified the / operator and results in erroneous output when
+run under python3.
+
+This commit replaces instances of / with //, yielding the expected
+result in both versions of Python.

+Subject: [PATCH] arc stat/summary: guard access to l2arc MFU/MRU stats
+
+commit 085321621e79a75bea41c2b6511da6ebfbf2ba0a added printing MFU
+and MRU stats for 2.1 user space tools, but those keys are not
+available in the 2.0 module. That means it may break the arcstat and
+arc_summary tools after upgrade to 2.1 (user space), before a reboot
+to the new 2.1 ZFS kernel-module happened, due to python raising a
+KeyError on the dict access then.
+
+Move those two keys to a .get accessor with `0` as fallback, as it
+should be better to show some possible wrong data for new stat-keys
+than throwing an exception.
+
+Signed-off-by: Thomas Lamprecht <t.lamprecht@proxmox.com>
+
+also move l2_mfu_asize  l2_mru_asize l2_prefetch_asize
+l2_bufc_data_asize l2_bufc_metadata_asize to .get accessor
+(these are only present with a cache device in the pool)
