- Subject: [PATCH 03/19] y2038: introduce linux/compat_time.h header
- Authentication-results: sourceware.org; auth=none
- References: <1430929826-318934-1-git-send-email-arnd at arndb dot de>
We want to reuse all the compat syscall handling for native syscalls
on 32-bit architectures when dealing with 32-bit time_t types.
This moves all time-related system call declarations from
include/linux/compat.h to include/linux/compat_time.h, along
with the associated data structures and typedefs.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
