Subject: [PATCH v6 00/14] Still more coroutine and various fixes in block layer
Date: Fri, 25 Nov 2022 08:35:04 -0500 [thread overview]
Message-ID: <20221125133518.418328-1-eesposit@redhat.com> (raw)
This is a dump of all minor coroutine-related fixes found while looking
around and testing various things in the QEMU block layer.
Patches aim to:
- add missing coroutine_fn annotation to the functions
- simplify to avoid the typical "if in coroutine: fn()
// else create_coroutine(fn)" already present in generated_co_wraper
functions.
- make sure that if a BlockDriver callback is defined as coroutine_fn, then
it is always running in a coroutine.
This serie is based on Kevin Wolf's series "block: Simplify drain".
Based-on: <20221108123738.530873-1-kwolf@redhat.com>

v6:
* use different naming for block-coroutine-wrapper annotations
* fix minor typos and patch odering
v5:
* add missing reviewed-by from Paolo
* minor indentation fixes
* use when possible _co_, but do not create new g_c_w. It will be done in
future series
* introduce QEMU_IN_COROUTINE
* reorder patches
* rebase on kevin block branch + v2 from "block: Simplify drain"
v4:
* use v2 commit messages
* introduce coroutine_wrapper to simplify patches
v3:
* Remove patch 1, base on kevin "drain semplification serie"
v2:
* clarified commit message in patches 2/3/6 on why we add coroutine_fn
Emanuele Giuseppe Esposito (14):
block-io: introduce coroutine_fn duplicates for
bdrv_common_block_status_above callers
block-copy: add missing coroutine_fn annotations
nbd/server.c: add missing coroutine_fn annotations
block-backend: replace bdrv_*_above with blk_*_above
block/vmdk: add missing coroutine_fn annotations
block: avoid duplicating filename string in bdrv_create
block: distinguish between bdrv_create running in coroutine and not
block: bdrv_create_file is a coroutine_fn
block: rename generated_co_wrapper in co_wrapper_mixed
block-coroutine-wrapper.py: introduce co_wrapper
block-coroutine-wrapper.py: default to main loop aiocontext if
function does not have a BlockDriverState parameter
block-coroutine-wrapper.py: support also basic return types
block: convert bdrv_create to co_wrapper
block/dirty-bitmap: convert coroutine-only functions to co_wrapper
