to give pollution compatible with <nfs/nqfs.h>. At least mount_nfs.c
previously had to #define KERNEL before including <nfs/nfs.h> to get
this pollution, but this gave other pollution.
Moved comment about NFSINT_SIGMASK to immediately before the code that
it applies to.
depend on <sys/types.h> forward declaring common ones.
Added an underscore to `sin' in prototypes to avoid warnings for the
conflict with the ANSI sin().
a BSD4.4Lite1 feature, not a FreeBSD feature. <sys/ioctl.h> is a
compatibility misfeature.
Moved NPCI ifdef. This file didn't compile if NPCI <= 0. It shouldn't
be configured in that case, but it is easy to support (mis)configuration
of drivers without buses by generating null objects, and many drivers
do it.
Removed unused includes.
prematurely when there was a hole (for a cdrom or an unused
interface) in the sequence of wd drives. This caused non-free
wd units to be probed as atapi drives. There was no problem
provided the atapi probe failed correctly.
Fix the SCIOCGETDEVINFO code so that it compiles, and while I'm at it,
add support for human-readable device names so that I don't have
to call devname(3) on the scd->dev to get it.
in kernel Makefiles. Nothing in /usr/include is used (provided
relative paths for sys/* and <machine> can be found), so there is
no need for the -I/usr/include kludge as in kernel Makefiles.
since pkh made tunctl static in revision 1.17 these are already
guaranteed to be zero'd and tunattach will only be called once.
Pointed out by: Bruce Evans and Bill Fenner
to look up information about that device. Right now, all it does
is give back the dev_t for the device, if known, since that's all
I needed, but hopefully the SCSI mavens will come up with a more generally
useful structure.
MUST be PG_BUSY. It is bogus to free a page that isn't busy,
because it is in a state of being "unavailable" when being
freed. The additional advantage is that the page_remove code
has a better cross-check that the page should be busy and
unavailable for other use. There were some minor problems
with the collapse code, and this plugs those subtile "holes."
Also, the vfs_bio code wasn't checking correctly for PG_BUSY
pages. I am going to develop a more consistant scheme for
grabbing pages, busy or otherwise. For now, we are stuck
with the current morass.
