From: Arnd Bergmann Date: Sun, 27 Sep 2015 20:45:18 +0000 (-0400) Subject: staging/lustre: use 64-bit time for debugfs output X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=74e489aa9cce1ec8f8a44ecc1651cf06b61db204;p=openwrt%2Fstaging%2Fblogic.git staging/lustre: use 64-bit time for debugfs output This time is only printed in debugfs, and can be easily converted to 64-bit to avoid overflowing on 32-bit systems in 2038.
