[PATCH] x86-64: Define IGNORE_IOCTL() macro for compat_ioctls
Define a new IGNORE_IOCTL() to let a compat ioctl not be warned about even when
it is not implemented.
This is the same as COMPATIBLE_IOCTL internally, but better self documentng.
Valid reasons to use this:
- It is implemented with ->compat_ioctl on some device, but programs
call it on others too.
- The ioctl is not implemented in the native kernel, but programs
call it commonly anyways.
Most other reasons are not valid.
