With the current code, the following sequence won't work : echo timer > trigger echo 0 > delay_off * at this point we call ** led_delay_off_store ** led_blink_set *** stop timer ** led_blink_setup ** led_set_software_blink *** if !delay_on, led off *** if !delay_off, set led_set_brightness_nosleep <--- LED_BLINK_SW is set but timer is stop *** otherwise start timer/set LED_BLINK_SW flag echo xxx > brightness * led_set_brightness ** if LED_BLINK_SW *** if brightness=0, led off *** else apply brightness if next timer <--- timer is stop, and will never apply new setting ** otherwise set led_set_brightness_nosleep To fix that, when we delete the timer, we should clear LED_BLINK_SW.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
