First time compiling a -current kernel... hope I'm not missing
something obvious. I want vnode support in the new kernel, but I get
this when trying to compile /usr/src/sys/dev/vn/vn.c:
../../dev/vn/vn.c: In function `vnioctl':
../../dev/vn/vn.c:443: `VNIOCSET' undeclared (first use this function)
../../dev/vn/vn.c:443: (Each undeclared identifier is reported only once
../../dev/vn/vn.c:443: for each function it appears in.)
../../dev/vn/vn.c:492: `VNIOCCLR' undeclared (first use this function)
../../dev/vn/vn.c:510: warning: unreachable code at beginning of switch statement
*** Error code 1
Looking in <sys/vnioctl.h>:
/*
* Before you can use a unit, it must be configured with VNIOCSET.
* The configuration persists across opens and closes of the device;
* an VNIOCCLR must be used to reset a configuration. An attempt to
* VNIOCSET an already active unit will return EBUSY.
*/
#define VNIOCATTACH _IOWR('F', 0, struct vn_ioctl) /* attach file */
#define VNIOCDETACH _IOWR('F', 1, struct vn_ioctl) /* detach disk */
#define VNIOCGSET _IOWR('F', 2, u_long ) /* set global option */
#define VNIOCGCLEAR _IOWR('F', 3, u_long ) /* reset --//-- */
#define VNIOCUSET _IOWR('F', 4, u_long ) /* set unit option */
#define VNIOCUCLEAR _IOWR('F', 5, u_long ) /* reset --//-- */
The #defines for VNIOCSET and VNIOCCLR are nowhere to be found.
