NAME

struct_ccw_device - channel attached device

SYNOPSIS

struct ccw_device {
  spinlock_t * ccwlock;
  struct ccw_device_id id;
  struct ccw_driver * drv;
  struct device dev;
  int online;
  void (* handler) (struct ccw_device *, unsigned long, struct irb *);
};

MEMBERS

ccwlock

: pointer to device lock

: id of this device

drv

: ccw driver for this device

dev

: embedded device structure

online

: online status of device

handler

: interrupt handler

DESCRIPTION

handler is a member of the device rather than the driver since a driver can have different interrupt handlers for different ccw devices (multi-subchannel drivers).
