d53d7e4461 Fix an uninitialized variable in the `dangerously dedicated disk' case. 1998-10-30 07:15:52 +00:00

e79dcdb69f Add the ability to specify where on the at_shutdown queue a handler is 
installed.

Remove cpu_power_down, and replace it with an entry at the end of the
SHUTDOWN_FINAL queue in the only place it's used (APM).

Submitted by:	Some ideas from Bruce Walter <walter@fortean.com>

0fcabcf90e Do not disable the ISA compatibility window if it is the same value as 
that set for our PCI IO address space.  This can happen on the BT-946.

af8d56d484 Fix this correctly - check if mfs_getimage() succeeds before settings 
the MFS root unconditionally, just as on the x86.

573dce4383 Take MFS_ROOT out for now; for some reason, the alpha GENERIC chokes 
and dies if it can't find the MFS root whereas the x86 one seems to sail
past.  Looking at the code, I can't see how either one works, so I'm
confused. :)

b7cb0214c9 Make the BTX loader much more quiet about what it's doing. This removes 
most of the "what the (*^&%(*^ was that?" stuff that normally flies by.

fe9b0651f9 Remove the V_SAVEMETA flag, nothing uses it any more now that msdosfs and 
ext2fs call vtruncbuf() directly.  This simplifies and cleans up
vinvalbuf() a little.

0c010ce2d1 error return assignment was less than ideal. Fix the part that caused 
warnings to be the same as the ffs code.  Previously, any error from
the UFS_UPDATE() call was lost (I think).

c002ba1c81 Use vtruncbuf() to clean out cached blocks on a file shorten rather than 
the more expensive vinvalbuf(), based on the FFS version of the same
routine.  I don't have any ext2fs filesystems to test this on.

e7e02b314f Make the definition of __printf0like() vary according to the value 
of __FreeBSD_cc_version, so that its use is safe with older compilers
and with non-FreeBSD compilers.

dc7a9e560a Change the way unmounting happens to guarantee that the 
client programs are allowed to finish up (coda_call is
forced to complete) and release their locks.  Thus there
is a reasonable chance that the vflush implicit in the
unmount will not get hung on held locks.

45c6ebc96d Simplify the "is a character ready" test, so that we don't return a false 
negative for keypresses with zero ascii values.  This is in line with the
comconsole test, rather than being more ambitious.

bd7a76a938 Oops, the redundant tests for major numbers weren't redundant here. 
They checked for the magic major number for the "device" behind mfs
mount points.  Use a more obvious check for this device.

285a46e7e4 Updated the major number check in vfs_object_create(). It's not 
clear if the check is necessary, but vfs_object_create() is called
for all vnodes and it was silly to create objects for VBLK vnodes
that don't even have a driver.

558766fa94 Don't follow null bdevsw pointers. The `major(dev) < nblkdev' test rotted 
when bdevsw[] became sparse.  We still depend on magic to avoid having to

Removed a redundant `major(dev) < nblkdev' test instead of updating it.

Don't follow a garbage bdevsw pointer for attempts to swap on empty
regular files.  This case currently can't happen.  Swapping on regular
files is ifdefed out in swapon() and isn't attempted for empty files
in nfs_mountroot().

b17bde009a Fixed device number checking in bdevvp(): 
- dev != NODEV was checked for, but 0 was returned on failure.  This was
  fixed in Lite2 (except the return code was still slightly wrong (ENODEV
  instead of ENXIO)) but the changes were not merged.  This case probably
  doesn't actually occur under FreeBSD.
- major(dev) was not checked to have a valid non-NULL bdevsw entry.  This
  caused panics when the driver for the root device didn't exist.

Fixed minor misformattings in bdevvp().  Rev.1.14 consisted mainly of
gratuitous reformattings that seem to have caused many Lite2 merge
errors.
