RH-Commit: [2/2] 29c3128a158b7c49fa79c141a9adcc12693f7de4 (ebblake/centos-qemu-kvm)
|
|
|
|
Prevent regressions when using NBD with TLS in the presence of
|
|
iothreads, adding coverage the fix to qio channels made in the
|
|
previous patch.
|
|
|
|
The shell function pick_unused_port() was copied from
|
|
nbdkit.git/tests/functions.sh.in, where it had all authors from Red
|
|
Hat, agreeing to the resulting relicensing from 2-clause BSD to GPLv2.
