------------------------------------------------------ From: Helge Deller deller@gmx.de Subject: mm: add lockdep annotation to pgdat_init_all_done_comp completer Date: Fri, 11 Aug 2023 18:06:19 +0200

Add the missing lockdep annotation to avoid this kernel warning:

smp: Brought up 1 node, 1 CPU INFO: trying to register non-static key. The code is fine but needs lockdep annotation, or maybe you didn't initialize this object before use?' turning off the locking correctness validator.
