6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jens Axboe axboe@kernel.dk
commit 957860cbc1dc89f79f2acc193470224e350dfd03 upstream.
A previous commit changed how requests are linked in the plug structure, but unlike the previous method, it uses a new type for it rather than struct request. The latter is available even for !CONFIG_BLOCK, while struct rq_list is now. Move it outside CONFIG_BLOCK.
