From 986ef135c2afce959971b0086fc04e0f9f654120 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sun, 27 Sep 2015 16:45:28 -0400 Subject: [PATCH] staging/lustre: use 64-bit times for ptlrpc sec expiry The exp_flvr_expire and imp_sec_expire are defined as 'unsigned long', which doesn't overflow until 2106, but to be on the safe side, this changes the code to use time64_t like we do everywhere else.
