commit 067311d33e650adfe7ae23765959ddcc1ba18510 upstream.
The maple tree node is overloaded to keep status as well as the active
node. This, unfortunately, results in a re-walk on underflow or overflow.
Since the maple state has room, the status can be placed in its own
Hey,
We had some problems with the hdmi on the imx8mp and wanted to leave, what we
found out about it, somewhere for others to find it.
The problem was that our hdmi display sometimes stayed blank after hot plugging
and sometimes at startup. On older kernel versions 6.6 we did not have the

commit a2587a7e8d37885dc063255f5400a66299b42e48 upstream.
Add test for mtree_dup().
Test by duplicating different maple trees and then comparing the two
trees. Includes tests for duplicating full trees and memory allocation
failures on different nodes.

commit 24662decdd44645e8f027d7912be962dd461d1aa upstream.
Since the pivot being set is now reliable, the optimized loop no longer
needs to find the node end. The redundant check for a dead node can also
be avoided as there is no danger of using the wrong pivot since the
