From f5cc6898650210a90669437d2d9a3fd564ff7d88 Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Fri, 7 Jul 2017 16:14:45 +0200 Subject: [PATCH] libceph: use alloc_pg_mapping() in __decode_pg_upmap_items() ... otherwise we die in insert_pg_mapping(), which wants pg->node to be empty, i.e. initialized with RB_CLEAR_NODE.
