Subject: [PATCH 17/28] maple_tree: inline mas_wr_spanning_rebalance()
Date: Thu, 15 Jan 2026 14:36:36 -0500	[thread overview]
Message-ID: <20260115193647.1695937-18-Liam.Howlett@oracle.com> (raw)
In-Reply-To: <20260115193647.1695937-1-Liam.Howlett@oracle.com>

Now that the spanning rebalance is small, fully inline it in
mas_wr_spanning_store().

No functional change.
