Subject: [PATCH] net: ieee802154: mcr20a: convert to use maple tree register cache
Date: Fri, 2 Feb 2024 01:46:11 -0500	[thread overview]
Message-ID: <20240202064611.39346-1-liubo03@inspur.com> (raw)

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache.
