# The above is needed to give us access to "RUN --security=insecure" below, and
# this is needed to make fellow tests succeed. Otherwise the docker sandbox
# will prevent access to io_uring:

# fellow: io_uring try: FATAL, got -1 (Operation not permitted)
# Wrong turn in try_flag(), fellow_io_uring.c line 262: Unexpected io_uring error. Is it available?
#   errno = 1 (Operation not permitted)
