[PATCH v4 2/3] dma-buf: heaps: Parameterize heap name in __add_cma_heap()

Prepare for the introduction of a fixed-name CMA heap by replacing the unused void pointer parameter in __add_cma_heap() with the heap name. Reviewed-by: Maxime Ripard Signed-off-by: Jared Kangas --- drivers/dma-buf/heaps/cma_heap.c | 18 +++--- 1 file changed, 11 insertions(+), 7

[PATCH v4 3/3] dma-buf: heaps: Give default CMA heap a fixed name

simplify naming, unconditionally name it "default_cma_region", but keep a legacy node in place backed by the same underlying allocator for backwards compatibility. Reviewed-by: Maxime Ripard Signed-off-by: Jared Kangas --- Documentation/userspace-api/dma-buf-heaps.rst | 7 +--

[PATCH v4 1/3] Documentation: dma-buf: heaps: Fix code markup

Code snippets should be wrapped in double backticks to follow reStructuredText semantics; the use of single backticks uses the :title-reference: role by default, which isn't quite what we want. Add double backticks to code snippets to fix this. Reviewed-by: Maxime Ripard Signed-off-by:
