From 473c4e01029f6692be7ddc0e7f9b75dc933c7057 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sun, 27 Sep 2015 16:45:13 -0400 Subject: [PATCH] staging/lustre: use 64-bit ibn_incarnation computation ibn_incarnation is a 64-bit value, but using timeval to compute it will cause an overflow in 2038. This changes it to use ktime_get_real_ts64() instead.
