From 8cc980713ec9e6847896891c54562ad815c33424 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sun, 27 Sep 2015 16:45:29 -0400 Subject: [PATCH] staging/lustre: use 64-bit times for ptlrpc_sec Here we use an unsigned long to store the timeout for gc, which is probably safe until 2106, but this patch converts it to use ktime_get_real_seconds() and time64_t for consistency.
