From 6020190e8f5a94bee7e65a787a1b784cb0f4c4d0 Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Fri, 14 May 2010 09:31:22 -0700 Subject: [PATCH] Use do_posix_clock_monotonic_gettime() as described by comment. While this does incur slightly more overhead we should be using do_posix_clock_monotonic_gettime() for gethrtime() as described by the existing comment. --- module/spl/spl-time.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/module/spl/spl-time.c b/module/spl/spl-time.c index 2973ae82d5..6806dcf71f 100644 --- a/module/spl/spl-time.c +++ b/module/spl/spl-time.c @@ -60,9 +60,10 @@ __gethrtime(void) { /* Deal with signed/unsigned mismatch */ return (hrtime_t)(res & ~(1ULL << 63)); #else - uint64_t j = get_jiffies_64(); + struct timespec ts; - return (hrtime_t)(j * (NSEC_PER_SEC / HZ)); + do_posix_clock_monotonic_gettime(&ts); + return (hrtime_t)((ts.tv_sec * NSEC_PER_SEC) + ts.tv_nsec); #endif } EXPORT_SYMBOL(__gethrtime);
