| * command such as QCMD(Q_GETQUOTA, USRQUOTA) cannot be resolved on platforms where "int" is 32bit, as it is |
| * larger than INT_MAX. Yikes, because that are basically all platforms Linux supports. Let's add a wrapper |
| * that explicitly takes its arguments as unsigned 32bit, and then converts the shift result explicitly to |
| * int, acknowledging the undefined behaviour of the kernel headers. This doesn't remove the undefined |
| * behaviour, but it stops ubsan from complaining about it. */ |
