Youshchenko" <yoush@...msu.su>, linuxpps@...enneenne.com, Rodolfo Giometti <giometti@...eenne.com>, Alexander Gordeev <lasaine@....cs.msu.su> Subject: [PATCHv5 09/17] pps: do not disable interrupts for idr operations Now pps_idr_lock is never used in interrupt context so replace spin_lock_irq/spin_unlock_irq with plain spin_lock/spin_unlock.
