block: GRAPH_RDLOCK for functions only called by co_wrappers (2022-12-14 13:13:07 +0100)
----------------------------------------------------------------
Block layer patches
- Code cleanups around block graph modification
- Simplify drain
- coroutine_fn correctness fixes, including splitting generated
coroutine wrappers into co_wrapper (to be called only from
non-coroutine context) and co_wrapper_mixed (both coroutine and
non-coroutine context)
- Introduce a block graph rwlock
----------------------------------------------------------------
Emanuele Giuseppe Esposito (21):
block-io: introduce coroutine_fn duplicates for bdrv_common_block_status_above callers
block-copy: add coroutine_fn annotations
nbd/server.c: add coroutine_fn annotations
block-backend: replace bdrv_*_above with blk_*_above
block/vmdk: add 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: support functions without bs arg
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
graph-lock: Implement guard macros
async: Register/unregister aiocontext in graph lock list
block: wrlock in bdrv_replace_child_noperm
block: remove unnecessary assert_bdrv_graph_writable()
block: assert that graph read and writes are performed correctly
block-coroutine-wrapper.py: introduce annotations that take the graph rdlock
block: use co_wrapper_mixed_bdrv_rdlock in functions taking the rdlock
Kevin Wolf (25):
qed: Don't yield in bdrv_qed_co_drain_begin()
test-bdrv-drain: Don't yield in .bdrv_co_drained_begin/end()
block: Revert .bdrv_drained_begin/end to non-coroutine_fn
block: Remove drained_end_counter
block: Inline bdrv_drain_invoke()
block: Fix locking for bdrv_reopen_queue_child()
block: Drain individual nodes during reopen
block: Don't use subtree drains in bdrv_drop_intermediate()
stream: Replace subtree drain with a single node drain
block: Remove subtree drains
block: Call drain callbacks only once
block: Remove ignore_bds_parents parameter from drain_begin/end.
block: Drop out of coroutine in bdrv_do_drained_begin_quiesce()
block: Don't poll in bdrv_replace_child_noperm()
block: Remove poll parameter from bdrv_parent_drained_begin_single()
block: Factor out bdrv_drain_all_begin_nopoll()
Import clang-tsa.h
clang-tsa: Add TSA_ASSERT() macro
clang-tsa: Add macros for shared locks
configure: Enable -Wthread-safety if present
test-bdrv-drain: Fix incorrrect drain assumptions
block: Fix locking in external_snapshot_prepare()
graph-lock: TSA annotations for lock/unlock functions
Mark assert_bdrv_graph_readable/writable() GRAPH_RD/WRLOCK
block: GRAPH_RDLOCK for functions only called by co_wrappers
Paolo Bonzini (1):
graph-lock: Introduce a lock to protect block graph operations
Vladimir Sementsov-Ogievskiy (4):
block: Inline bdrv_detach_child()
block: drop bdrv_remove_filter_or_cow_child
block: bdrv_refresh_perms(): allow external tran
block: refactor bdrv_list_refresh_perms to allow any list of nodes
