linux.git/arch/nds32/include/uapi/asm, branch v4.20 Linux kernel source tree y2038: Remove stat64 family from default syscall set 2018-08-29T13:42:20+00:00 Arnd Bergmann arnd@arndb.de 2018-04-13T10:19:47+00:00 bf4b6a7d371e4d2a23a9d545bee908f67d32b3ea New architectures should no longer need stat64, which is not y2038 safe and has been replaced by statx(). This removes the 'select __ARCH_WANT_STAT64' statement from asm-generic/unistd.h and instead moves it into the respective asm/unistd.h UAPI header files for each architecture that uses it today. In the generic file, the system call number and entry points are now made conditional, so newly added architectures (e.g. riscv32 or csky) will never need to carry backwards compatiblity for it. arm64 is the only 64-bit architecture using the asm-generic/unistd.h file, and it already sets __ARCH_WANT_NEW_STAT in its headers, and I use the same #ifdef here: future 64-bit architectures therefore won't see newstat or stat64 any more. They don't suffer from the y2038 time_t overflow, but for consistency it seems best to also let them use statx(). Signed-off-by: Arnd Bergmann <arnd@arndb.de> 
New architectures should no longer need stat64, which is not y2038
safe and has been replaced by statx(). This removes the 'select
__ARCH_WANT_STAT64' statement from asm-generic/unistd.h and instead
moves it into the respective asm/unistd.h UAPI header files for each
architecture that uses it today.

In the generic file, the system call number and entry points are now
made conditional, so newly added architectures (e.g. riscv32 or csky)
will never need to carry backwards compatiblity for it.

arm64 is the only 64-bit architecture using the asm-generic/unistd.h
file, and it already sets __ARCH_WANT_NEW_STAT in its headers, and I
use the same #ifdef here: future 64-bit architectures therefore won't
see newstat or stat64 any more. They don't suffer from the y2038 time_t
overflow, but for consistency it seems best to also let them use statx().
