Subject: [PATCH 08/19] nfsd: use ktime_get_seconds() for timestamps
Date: Mon, 11 Nov 2019 21:16:28 +0100 [thread overview]
Message-ID: <20191111201639.2240623-9-arnd@arndb.de> (raw)
In-Reply-To: <20191111201639.2240623-1-arnd@arndb.de>
The delegation logic in nfsd uses the somewhat inefficient
seconds_since_boot() function to record time intervals.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
