Uhm, doesn't sys_sync_file_range2 break that?
+asmlinkage long compat_sys_sync_file_range2(int fd, unsigned int flags,
+ unsigned offset_hi, unsigned offset_lo,
+ unsigned nbytes_hi, unsigned nbytes_lo)
How about:
asmlinkage long compat_sys_sync_file_range2(unsigned offset_hi,
unsigned offset_lo, unsigned nbytes_hi, unsigned nbytes_lo,
int fd, unsigned int flags)
Also, you might want to put something in the syscall file about signed
vs unsigned arguments and how they behave with 32-on-64 systems.
