Hi all!
This is inspired by Kevin's
"block: Fix blk->in_flight during blk_wait_while_drained()" series.
So, like it's now done for block-backends, let's expand
in_flight-protected sections for bdrv_ interfaces, including
coroutine_enter and BDRV_POLL_WHILE loop into these sections.
v2:
01: drop coroutine_fn from bdrv_is_allocated_above declaration
02-04: add Stefan's r-b
05: improve commit message
fix typo in bdrv_do_pdiscard name
add more "To be called between exactly one pair of
bdrv_inc/dec_in_flight()" comments
drop unused bs variable
fix bdrv_pdiscard_co_entry to use bdrv_do_pdiscard
06: similarly to 05, add additional comment to bdrv_is_allocated_above_co_entry
07-08: add Stefan's r-b
09: add "To be called between exactly one pair of bdrv_inc/dec_in_flight()" for
bdrv_make_zero_co_entry
Vladimir Sementsov-Ogievskiy (9):
block/io: refactor bdrv_is_allocated_above to run only one coroutine
block/io: refactor bdrv_co_ioctl: move aio stuff to corresponding
block
block/io: move flush and pdiscard stuff down
block/io: move bdrv_rw_co_entry and friends down
block/io: expand in_flight inc/dec section: simple cases
block/io: expand in_flight inc/dec section: block-status
block/io: add bdrv_do_pwrite_zeroes
block/io: move bdrv_make_zero under block-status
block/io: expand in_flight inc/dec section: bdrv_make_zero
