CVS commit: src/sys/sys

[Reinoud Zandijk <reinoud%netbsd.org@localhost>]

Module Name:    src
Committed By:   reinoud
Date:           Wed Feb 16 23:34:05 UTC 2005

Modified Files:
        src/sys/sys: fcntl.h

Log Message:
Add the KERNEL-only flag FKIOCTL (like its named in Solaris) to be passed
as extra flag to VOP_IOCTL() calls to indicate that addresses/data blocks
specified in the ioctl paramter like an address to a datablock to be filled
is for kernel use and not for userland.

The few ioctl calls that have this kind of variable-length parameter
passing can then decide if they ought to use copyout() or to use memcpy()
depending on this FKIOCTL flag.

Name and patch discussed on tech-kern.
