GONE_IN(9) FreeBSD Kernel Developer's Manual 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".
EXAMPLES
void
sample_init(void)
{

{
/* Attach code omitted. */
gone_in_dev(sc->dev, 14, "Giant-locked driver");
}
HISTORY
The gone_in functions first appeared in FreeBSD 11.
