io_uring: provide means of removing buffers We have IORING_OP_PROVIDE_BUFFERS, but the only way to remove buffers is to trigger IO on them. The usual case of shrinking a buffer pool would be to just not replenish the buffers when IO completes, and instead just free it. But it may be nice to have a way to manually remove a number of buffers from a given group, and IORING_OP_REMOVE_BUFFERS provides that functionality. Signed-off-by: Jens Axboe <axboe@kernel.dk>
