NAME
vfs_suser - check if credentials have superuser privileges for a mount pointSYNOPSIS
In sys/param.h In sys/systm.h In sys/mount.h Ft int Fn vfs_suser struct mount *mp struct thread *tdDESCRIPTION
The Fn vfs_suser function checks if the credentials given include superuser powers for the given mount point. It will check to see if the thread passed in has the same credentials as the user that mounted the file system. If so, it returns 0, otherwise it returns what priv_check9 would have returned.RETURN VALUES
The Fn vfs_suser function returns 0 if the user has superuser powers and Er EPERM otherwise. This is the reverse logic of some other implementations of Fn suser in which a TRUE response indicates superuser powers.SEE ALSO
