Though most, if not all the pwm based backlight\ndevices start flickering at lower brightness value. And also for each\ndevice there exists a brightness value below which the backlight appears\nto be turned off though the value is not equal to zero.\n\nIf the range of brightness for a device is from zero to max_brightness. A\ngraph is plotted for brightness Vs intensity for the pwm based backlight\ndevice has to be a linear graph.\n\nintensity\n\t | /\n\t | /\n\t | /\n\t |/\n\t ---------\n\t 0\tmax_brightness\n\nBut pratically on measuring the above we note that the intensity of\nbacklight goes to zero(OFF) when the value in not zero almost nearing to\nzero(some x%). so the graph looks like\n\nintensity\n\t | /\n\t | /\n\t | /\n\t | |\n\t ------------\n\t 0 x\t max_brightness\n\nIn order to overcome this drawback knowing this x% i.e nothing but the low\nthreshold beyond which the backlight is off and will have no effect, the\nbrightness value is being offset by the low threshold value(retaining the\nlinearity of the graph). Now the graph becomes\n\nintensity\n\t | /\n\t | /\n\t | /\n\t | /\n\t -------------\n\t 0\t max_brightness\n\nWith this for each and every digit increment in the brightness from zero\nthere is a change in the intensity of backlight.

Because of multiplexing, it is necessary to know\nboth time_enabled, time_running to be able to scale counts correctly.\n\nIn this second version of the patch, we maintain a shadow\ncopy of ctx-\u003etime which allows us to compute ctx-\u003etime without\ncalling update_context_time() from NMI context. We avoid the\nissue that update_context_time() must always be called with\nctx-\u003elock held.\n\nWe do not keep shadow copies of the other event timings\nbecause if the lead event is overflowing then it is active\nand thus it\u0027s been scheduled in via event_sched_in() in\nwhich case neither tstamp_stopped, tstamp_running can be modified.\n\nThis timing logic only applies to samples when PERF_SAMPLE_READ\nis used.\n\nNote that this patch does not address timing issues related\nto sampling inheritance between tasks.

That asserts turns out to trigger a lot\nwhen running fsx on filesystems with small block sizes. The reason for\nthat is that the assert is simply incorrect. !mapped and uptodate\njust mean this buffer covers a hole, and whenever we do a set_page_dirty\nwe mark all blocks in the page dirty, no matter if they have data or\nnot.
