GONE_IN(9)

NAME
gone_in, gone_in_dev - deprecation notice functions

SYNOPSIS
#include <sys/systm.h>
void
gone_in(int major, const char *msg);
void
gone_in_dev(device_t dev, int major, const char *msg);

DESCRIPTION
The gone_in() functions are used to provide a notice that the kernel is using a driver or some other functionality that is deprecated, and will be removed in a future FreeBSD release. The notice is sent to the kernel dmesg(8) log and will appear on the console. The major argument specifies the major version of the FreeBSD release that will remove the deprecated functionality.

In releases before major the deprecation notice states “ Deprecated code (to be removed in FreeBSD major): msg ”. In releases equal to and after major the notice states “ Obsolete code will be removed soon: msg ”.

    int

    {
    	/* Attach code omitted. */
            gone_in_dev(sc->dev, 14, "Giant-locked driver");
    }
