Subject: [PATCH v2 18/29] maple_tree: inline mas_wr_spanning_rebalance()
Date: Wed, 21 Jan 2026 11:45:15 -0500	[thread overview]
Message-ID: <20260121164526.2093265-19-Liam.Howlett@oracle.com> (raw)
In-Reply-To: <20260121164526.2093265-1-Liam.Howlett@oracle.com>

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

No functional change.
