From 3ed5c2f0ee3da0342bcd412818f2dcc186d788ac Mon Sep 17 00:00:00 2001 From: Michael Holzheu Date: Fri, 30 Jun 2017 20:31:47 +0200 Subject: [PATCH] criu/files: Fix wait_fds_event() for 64 bit platforms The htole64() function returns a 64 bit value. This is stored in a 32 bit integer in wait_fds_event() which results in 0 for big-endian 64 bit platforms. The fuxtex() system call also requires 32 bit values. Fix this and use htole32() also for 64 bit platforms.
