Veaceslav Falico ec6f809ff6 af_packet: block BH in prb_shutdown_retire_blk_timer() ... Currently we're using plain spin_lock() in prb_shutdown_retire_blk_timer(), however the timer might fire right in the middle and thus try to re-aquire the same spinlock, leaving us in a endless loop. To fix that, use the spin_lock_bh() to block it. Fixes: f6fb8f100b ("af-packet: TPACKET_V3 flexible buffer implementation.") CC: "David S.
