File bug-1063051_0002-refactor-toolcontext-add-struct-cmd_context_initiali.patch of Package lvm2.openSUSE_Leap_42.3_Update

From 52ac7a78fde508fc1ffb2c15b15ee9aa30bd2b3d Mon Sep 17 00:00:00 2001

Subject: [PATCH 03/10] refactor: toolcontext: add struct
 cmd_context_initialized_parts

Add struct cmd_context_initialized_parts to wrap up information
about which cmd context pieces are initialized and add variable
of this struct type into struct cmd_context.

Also, move existing "config_initialized" variable that was directly
part of cmd_context into the new cmd_context.initialized wrapper.

We'll be adding more items into the struct cmd_context_initialized_parts
with subsequent patches...

(cherry picked from commit 6b0c464a3462c568931c22fe71cc4f80b7ead508)
