Subject: [PATCH blktests v2 11/12] common: Use sysfs instead of modinfo for
 _have_module_param()
In-Reply-To: <20190717171259.3311-1-logang@deltatee.com>
References: <20190717171259.3311-1-logang@deltatee.com>
Message-ID: <20190717171259.3311-12-logang@deltatee.com>

Using modinfo fails if the given module is built-in.

Instead, if the module is already in the kernel, check for the
parameter in sysfs.
