Subject: Fix: do not use bdi_unknown_name symbol
X-Git-Url: http://git.lttng.org/?a=commitdiff_plain;h=5873cbc67601a95b53e8c87fbeafb31910485fd0;hp=5873cbc67601a95b53e8c87fbeafb31910485fd0;p=lttng-modules.git

Fix: do not use bdi_unknown_name symbol

Use the GPL-exported bdi_dev_name introduced in kernel 5.7. Do not use
static inline bdi_dev_name in prior kernels because it uses the bdi_unknown_name
symbol which is not exported to GPL modules.
