One more thing I just remembered: I think we want this behavior for all new 32-bit architectures, it was a bug to call compat_sys_openat for the generic syscall table, as we don't support 32-bit off_t. Could you split this out into a separate patch that does these changes: - change the default asm-generic/unistd.h to use sys_openat/sys_open_by_handle_at - change tile to override those two to keep the current (suboptimal) behavior - change the force_o_largefile() definition so it defaults to true for all future architectures. The easiest way is probably to add a Kconfig symbol for this that gets selected by all 32-bit architectures, so we can use #define force_o_largefile() ((BITS_PER_LONG != 32) || !IS_ENABLED(CONFIG_ARCH_32BIT_OFF_T)) Arnd
