"scheduling while atomic" BUG in iscsid since commit 1b66d253610c7

[Marc Dionne]

The issue reported here:
    https://lkml.org/lkml/2020/7/28/1085
is still present as of 5.9-rc3; it was introduced in the 5.8 cycle.

When the problem occurs, iscsid crashes and iscsi volumes fail to come
up, which makes the machine quite sad if the volumes are critical to
its function.

Added CCs for iscsi related maintainers and lists suggested by get_maintainer.

Thanks,
Marc
