+Subject: [PATCH] Fix BlockThreshold Callback argument conversion once more
+
+The conversion was changed from "OssiiO" to "OssLLO". Unfortunately the
+arguments are unsigned long long, where the proper coversion character
+is 'K'.
+
+Fixes: https://gitlab.com/libvirt/libvirt-python/-/merge_requests/40
+Fixes: fd069ac85c8cf1593587dc9287a3d5eb6bd4bdb9
+Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1976109
