From 8dabe7245bbc134f2cfcc12cde75c019dab924cc Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 7 Jan 2019 00:33:08 +0100 Subject: y2038: syscalls: rename y2038 compat syscalls A lot of system calls that pass a time_t somewhere have an implementation using a COMPAT_SYSCALL_DEFINEx() on 64-bit architectures, and have been reworked so that this implementation can now be used on 32-bit architectures as well. The missing step is to redefine them using the regular SYSCALL_DEFINEx() to get them out of the compat namespace and make it possible to build them on 32-bit architectures. Any system call that ends in 'time' gets a '32' suffix on its name for that version, while the others get a '_time32' suffix, to distinguish them from the normal version, which takes a 64-bit time argument in the future. In this step, only 64-bit architectures are changed, doing this rename first lets us avoid touching the 32-bit architectures twice.
