Bug description:
This bug is for tracking purpose, this is not a regression for current
cycle as this issue exists for a long time.
It can be reproduced on zVM, zKVM and Ubuntu on LPAR
Steps:
1. git clone --depth=1 https://github.com/autotest/autotest-client-tests.git
2. make -C autotest-client-tests/aio_dio_bugs/src
3. sudo ./autotest-client-tests/aio_dio_bugs/src/aio-dio-invalidate-failure
poo
Result:
event res -22
From the code itself, it's expecting a -EIO return value:
if (event.res == -EIO) {
printf("invalidation returned -EIO, OK\n");
exit(0);
}
The actual return value is -22, which I think is -EINVAL
