Subject: [PATCH 10/18] maple_tree: print store type in mas_dump()
Date: Tue,  4 Jun 2024 10:41:37 -0700	[thread overview]
Message-ID: <20240604174145.563900-11-sidhartha.kumar@oracle.com> (raw)
In-Reply-To: <20240604174145.563900-1-sidhartha.kumar@oracle.com>

Knowing the store type of the maple state could be helpful for debugging.
Have mas_dump() print mas->store_type.
