Hi Jens,
The 1st patch fixes ublk_io_release(), and avoids warning from ublk
selftest(test_stress_04.sh).
The 2nd patch adds test case for this issue.
V2:
- release ublk char device in async way for avoiding dependency with
io_uring_release(), where sqe buffers may be unregistered finally
Ming Lei (2):
ublk: avoid ublk_io_release() called after ublk char dev is closed
ublk selftests: add --no_ublk_fixed_fd for not using registered ublk
char device
