[PATCH 17/18] block: Reorganize some declarations in block-backend-io.h |
Date: |
Tue, 17 May 2022 12:39:06 +0100 |
Keep generated_co_wrapper and coroutine_fn pairs together. This should
make it clear that each I/O function has these two versions.
Also move blk_co_{pread,pwrite}()'s implementations out of the header
file for consistency.
