Subject: insmod: do support -f
X-Git-Tag: v22~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2b2a503e4ff02b385ff6de9741a6b6afae910f11;p=thirdparty%2Fkmod.git

insmod: do support -f

The -f switch is accepted by insmod, but silently ignored. This
causes the user to wonder why things don't work. As insmod is
most often used with "evil" modules, -f is almost default and
thus needs to work.
