io_uring: kbuf: kill __io_kbuf_recycle()

2022-06-27T12:28:52+00:00

__io_kbuf_recycle() is only called in io_kbuf_recycle(). Kill it and tweak the code so that the legacy pbuf and ring pbuf code become clear Signed-off-by: Hao Xu Link: https://lore.kernel.org/r/20220622055551.642370-1-hao.xu@linux.dev Signed-off-by: Jens Axboe

io_uring: kill extra io_uring_types.h includes

2022-06-27T12:28:50+00:00
