io_uring: move a few private types to local headers 2022-07-25T00:39:14+00:00 Jens Axboe axboe@kernel.dk 2022-06-19T01:44:33+00:00 ad163a7e2562230c77102c60f668bac440e60cce Commit 3a3d47fa9cfd ("io_uring: make io_uring_types.h public") moved a bunch of io_uring types to a kernel wide header, so we could make tracing a bit saner rather than pass in a ton of arguments. However, there are a few types in there that are not really needed to be system wide. Move the cancel data and mapped buffers back to the appropriate io_uring local headers.

Commit 3a3d47fa9cfd ("io_uring: make io_uring_types.h public") moved
a bunch of io_uring types to a kernel wide header, so we could make
tracing a bit saner rather than pass in a ton of arguments.

However, there are a few types in there that are not really needed to
be system wide. Move the cancel data and mapped buffers back to the
