SVN rev 204464 on 2010-02-28 16:25:49Z by kib
In both if_tun and if_tap:
Do not do additional dev_ref() on the newly created interface in the
if_clone create method [1]. This reference is not needed and never
removed, causing struct cdevpriv leakage. Remove the setting of
SI_CHEAPCLONE flag as well, since it is unused.
For dev_clone handlers, create cdevs with the call make_dev_credf(MAKEDEV_REF)
instead of calling make_dev() and then dev_ref(), to avoid a race.
Call drain_dev_clone_events() at the module unload time after dev_clone
handler is deinstalled.
