Subject: common: Use sysfs instead of modinfo for _have_module_param()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=b059ba54b0436fcf74e91f2d7db8c1cf2f53fb6a;p=users%2Fsagi%2Fblktests.git

common: Use sysfs instead of modinfo for _have_module_param()

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.
