28 | * The wait_queue_token (autofs_wqt_t) is part of a structure which is passed |
| 29 | * back to the kernel via ioctl from userspace. On architectures where 32- and | |
| 30 | * 64-bit userspace binaries can be executed it's important that the size of | |
| 31 | * autofs_wqt_t stays constant between 32- and 64-bit Linux kernels so that we | |
| 32 | * do not break the binary ABI interface by changing the structure size. | |
