From: Eric W. Biederman <[email protected]> - unquoted
There is no need for open files in /proc/sys/XXX to hold
a reference count on the module that provides the file
to prevent module unload races. While there is code active
in the module p->used in the sysctl_table_header is incremented,
preventing the sysctl from being unregisted. Once the
sysctl is unregistered it cannot be found. Open files
are also not a problem as they revalidate the sysctl information
and bump p->used before accessing module code.
So setting de->owner is unnecessary, makes for a bad example
and gets in my way of removing ctl_table->de.
