This is a quite naive implementation to track whether a clocksource is enabled. I chose not to add a member in struct clocksource and use a flag instead.
I found that timekeeping.c is the only consumer for clocksource and I converted it to use clocksource_enable and clocksource_disable. Changes in v2: - removed the check on enable in timekeeping.c to ensure all clocksources are going through clocksource_enable - rework clocksource_enable to set CLOCK_SOURCE_USED when enable is successful if present Alexandre Belloni (2): clocksource: track usage clocksource: don't suspend/resume when unused include/linux/clocksource.h | 4 ++++ kernel/time/clocksource.c | 34 ++++++++++++++++++++++++++++++++-- kernel/time/timekeeping.c | 8 +++----- 3 files changed, 39 insertions(+), 7 deletions(-) -- 2.1.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
