The call makes only this space ! 35: available to the system for swap allocation. ! 36: .SH SEE ALSO ! 37: swapon(2), init(8) ! 38: .SH FILES ! 39: .DT ! 40: /dev/[ru][pk]?b standard paging devices ! 41: .SH BUGS ! 42: There is no way to stop paging and swapping on a device. ! 43: It is therefore not possible to make use of devices which may be ! 44: dismounted during system operation.
