[PATCH v3 02/10] include: Move compat_timespec/ timeval to compat_time.h

From: Deepa Dinamani
Date: Mon Jan 15 2018 - 21:19:55 EST

Next message: Deepa Dinamani: "[PATCH v3 08/10] fix get_timespec64() for y2038 safe compat interfaces"
Previous message: Deepa Dinamani: "[PATCH v3 09/10] change time types to new y2038 safe __kernel_* types"
In reply to: Deepa Dinamani: "[PATCH v3 09/10] change time types to new y2038 safe __kernel_* types"
Next in thread: Deepa Dinamani: "[PATCH v3 08/10] fix get_timespec64() for y2038 safe compat interfaces"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

All the current architecture specific defines for these
are the same. Refactor these common defines to a common
header file.

The new common linux/compat_time.h is also useful as it
will eventually be used to hold all the defines that
are needed for compat time types that support non y2038
safe types. New architectures need not have to define these
new types as they will only use new y2038 safe syscalls.
This file can be deleted after y2038 when we stop supporting
non y2038 safe syscalls.

The patch also requires an operation similar to:

git grep "asm/compat\.h" | cut -d ":" -f 1 | xargs -n 1 sed -i -e "s%asm/compat.h%linux/compat.h%g"
