---------------------------
What (Why):
- xt_recent: the old ipt_recent proc dir
(superseded by /proc/net/xt_recent)
When: January 2009 or Linux 2.7.0, whichever comes first
Why: Superseded by newer revisions or modules
Who: Jan Engelhardt <jengelh@medozas.de>
---------------------------
What: GPIO autorequest on gpio_direction_{input,output}() in gpiolib
When: February 2010
Why: All callers should use explicit gpio_request()/gpio_free().
