I probably just forgot. Sorry. v1: https://lists.nongnu.org/archive/html/qemu-block/2021-04/msg00584.html Changes in v2: - Letting `bdrv_try_set_aio_context()` return an error and then just discarding it conditionally is kind of not right. If we want to ignore the error, decide so from the start: Depending on `fixed_iothread`, pass either `errp` or `NULL`. - Patch 2: Reference output has changed because of 30ebb9aa920. git-backport-diff against v1: Key: [----] : patches are identical [####] : number of functional differences between upstream/downstream patch [down] : patch is downstream-only The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively 001/2:[0009] [FC] 'block/export: Conditionally ignore set-context error' 002/2:[0002] [FC] 'iotests/307: Test iothread conflict for exports' Max Reitz (2): block/export: Conditionally ignore set-context error iotests/307: Test iothread conflict for exports block/export/export.c | 5 ++++- tests/qemu-iotests/307 | 15 +++++++++++++++ tests/qemu-iotests/307.out | 8 ++++++++ 3 files changed, 27 insertions(+), 1 deletion(-)
