From 7dc5ba6254bb242a9f45e43549171a2d84d25e6a Mon Sep 17 00:00:00 2001 From: Liam Howlett Date: Mon, 7 Nov 2022 16:39:02 +0000 Subject: [PATCH] maple_tree: don't set a new maximum on the node when not reusing nodes In RCU mode, the node limits were being updated to the last pivot which may not be correct and would cause the metadata to be set when it shouldn't. Fix this by not setting a new limit in this case. Link: https://lkml.kernel.org/r/20221107163857.867377-1-Liam.Howlett@oracle.com Signed-off-by: Liam R.
