Subject: [PATCH 17/18] maple_tree: remove repeated sanity checks from mas_wr_append()
Date: Tue,  4 Jun 2024 10:41:44 -0700	[thread overview]
Message-ID: <20240604174145.563900-18-sidhartha.kumar@oracle.com> (raw)
In-Reply-To: <20240604174145.563900-1-sidhartha.kumar@oracle.com>

These sanity checks are now redundant as they are already checked in
mas_wr_store_type(). We can remove them from mas_wr_append().
