Revision 8372f4d83f96f35915106093cde4565836587123 authored by Liam Howlett on 27 February 2023, 17:36:03 UTC, committed by Andrew Morton on 06 April 2023, 01:06:21 UTC
The call to mte_set_dead_node() before the smp_wmb() already calls
smp_wmb() so this is not needed. This is an optimization for the RCU mode
of the maple tree.
