From b0da6d44157aa6e652de7634343708251ba64146 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Fri, 29 Apr 2016 22:29:26 +0100 Subject: asm-generic: Drop renameat syscall from default list The newer renameat2 syscall provides all the functionality provided by the renameat syscall and adds flags, so future architectures won't need to include renameat. Therefore drop the renameat syscall from the generic syscall list unless __ARCH_WANT_RENAMEAT is defined by the architecture's unistd.h prior to including asm-generic/unistd.h, and adjust all architectures using the generic syscall list to define it so that no in-tree architectures are affected.
