timers: Fix timer_migration interface which accepts any number as input
Poornima Nayek reported: | Timer migration interface /proc/sys/kernel/timer_migration in | 2.6.30-git9 accepts any numerical value as input. | | Steps to reproduce: | 1. echo -6666666 > /proc/sys/kernel/timer_migration | 2. cat /proc/sys/kernel/timer_migration | -6666666 | | 1. echo 44444444444444444444444444444444444444444444444444444444444 > /proc/sys/kernel/timer_migration | 2. cat /proc/sys/kernel/timer_migration | -1357789412 | | Expected behavior: Should 'echo: write error: Invalid argument' while | setting any value other then 0 & 1 Restrict valid values to 0 and 1.
