Revision 48cae885d5a896030588978f503c73c5ed5e62b1 authored by Stefan Weinhuber on 11 February 2009, 09:37:31 UTC, committed by Martin Schwidefsky on 11 February 2009, 09:37:40 UTC
In dasd_device_set_timer and dasd_block_set_timer we interpret the return value of mod_timer in a wrong way. If the timer expires in the small window between our check of timer_pending and the call to mod_timer, then the timer will be set, mod_timer returns zero and we will call add_timer for a timer that is already pending. As del_timer and mod_timer do all the necessary checking themselves, we can simplify our code and remove the race a the same time.
