this is an alternative way to insert mdev to be hotplug when sysfs is
not mounted.

are you sure about the dependency between echo and sysfs? It seems quite
unlikely to me. I'd guess the real problem is mdev failing to start
without sysfs.

real problem was missing mounting sysfs on /sys, but I wanted to keep the other
way of setting it instead of echo

Note that I was referring to your commit message.
After a second look I see that you also mount /proc in your patch, and I
guess that's what you meant to describe. Please update the commit
message (and subject) to actually match your patch.
