Subject: Where is the declaration of buffer used in kernel_param_ops .get
 functions?

These patches came up because I was looking for
the location of the declaration of the buffer used
in kernel/params.c struct kernel_param_ops .get
functions.

I didn't find it.

I want to see if it's appropriate to convert the
sprintf family of functions used in these .get
functions to sysfs_emit.

Patches submitted here:

Anyone know if it's appropriate to change the
sprintf-like uses in these functions to sysfs_emit
and/or sysfs_emit_at?
