/* Wrapper around the QCMD() macro of linux/quota.h that removes some undefined behaviour. A typical quota
|
|
* 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. */
