[PATCH] ntp: fix return value of adjtimex() calling for STA_INS/DEL

Hi, Since commit 6b43ae8a619d17c4935c3320d2ef9e92bdeed05d, adjtimex() system call returns TIME_OK even if STA_INS/DEL calling. But the man page says it should be TIME_INS/TIME_DEL, respectively. I have no idea except for such an ad-hoc fix. Signed-off-by: Seiichi Ikarashi --- a/kernel/time

[PATCH] clocksource: Add CPU info to clocksource watchdog reporting

The clocksource watchdog reporting was improved by 0b046b217ad4c6. I want to add the info of CPU where the watchdog detects a deviation because it is necessary to identify the trouble spot if the clocksource is TSC. Signed-off-by: Seiichi Ikarashi --- kernel/time/clocksource.c |4 ++-- 1
