* introduce fsetown(), fgetown(), fownsignal() - this sets/retrieves/signals the owner of descriptor, according to appropriate sematics of TIOCSPGRP/FIOSETOWN/SIOCSPGRP/TIOCGPGRP/FIOGETOWN/SIOCGPGRP ioctl; use these routines instead of custom code where appropriate * make every place handling TIOCSPGRP/TIOCGPGRP handle also FIOSETOWN/FIOGETOWN properly, and remove the translation of FIO[SG]OWN to TIOC[SG]PGRP in sys_ioctl() & sys_fcntl() * also remove the socket-specific hack in sys_ioctl()/sys_fcntl() and pass the ioctls down to soo_ioctl() as any other ioctl change discussed on tech-kern@

|
* as described by the firm_event structure.
|
|
* - If wskbd support is compiled in and a wskbd driver has been
|
|
* attached then the data is sent to it. Wskbd in turn may
|
|
* - Send the data in the wscons_event form to a process that
|
|
* has opened /dev/wskbd0
|
|
* - Feed the data to a virtual terminal.
