From 0fe2795516b9e1c59b58b02bdf8658698117ec4e Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 18 Jun 2018 16:07:59 +0200 Subject: posix-timers: Fix nanosleep_copyout() for CONFIG_COMPAT_32BIT_TIME Commit b5793b0d92c9 added support for building the nanosleep compat system call on 32-bit architectures, but missed one change in nanosleep_copyout(), which would trigger a BUG() as soon as any architecture is switched over to use it. Use the proper config symbol to enable the code path.
