From f140662f35a7332b5c3188ee667856323783ed5a Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Fri, 9 May 2014 18:27:34 +0400 Subject: [PATCH] crush: decode and initialize chooseleaf_vary_r Commit e2b149cc4ba0 ("crush: add chooseleaf_vary_r tunable") added the crush_map::chooseleaf_vary_r field but missed the decode part. This lead to misdirected requests caused by incorrect raw crush mapping sets.
