	There are opcodes that need ->async_data only in some cases and allocation it unconditionally may hurt performance. Add an option to opdef to make move the allocation part from the core io_uring to opcode specific code. Note, we can't just set opdef->async_size to zero because there are other helpers that rely on it, e.g. io_alloc_async_data().

2022-07-24	io_uring: move opcode table to opdef.c	Jens Axboe	1	-0/+2
	We already have the declarations in opdef.h, move the rest into its own file rather than in the main io_uring.c file. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2022-07-24	io_uring: move poll handling into its own file	Jens Axboe	1	-0/+40
	Add a io_poll_issue() rather than export the general task_work locking and io_issue_sqe(), and put the io_op_defs definition and structure into a separate header file so that poll can use it. Signed-off-by: Jens Axboe <axboe@kernel.dk>
