89600e8663 There was a situation where sendfile() might attempt to initiate I/O 
on a PG_BUSY page, due to a bug in its sequencing of a conditional.

aaba53da90 It is possible for a page in the cache to be busy. vm_pageout.c was not 
checking for this condition while it tried to free cache pages.  Fixed.

a7039a1d42 Add invariants to vm_page_busy() and vm_page_wakeup() to check for 
PG_BUSY stupidity.

c9fa34cf07 Clear PG_WRITEABLE in vm_page_cache(). This may or may not be a bug, 
but the bit should definitely be cleared.

8e3ad7c918 Depreciate vm_object_pmap_copy() - nobody uses it. Everyone uses 
vm_object_pmap_copt_1() now, apparently.

bc6d84a6a3 Get rid of unused old_m in vm_fault. Add INVARIANTS to test whether 
page is still busy after all the hell vm_fault goes through.. it is
    supposed to be, and printf() if it isn't.  don't panic, though.

377f9b28a6 Don't try to calculate B_CACHE for an NFS related bp that has a 
> 0 b_validend.  This will screw up small-writes, causing lots of
    little writes out the network.

    We will assume that NFS handles B_CACHE properly.

c679ae39a8 biosdisk.c 
Implement a new variable 'root_disk_unit' which supersedes
	'num_ide_disks' and makes it possible to explicitly set the
	root device unit number regardless of type considerations.

bootinfo.c
	If we can't calculate a dev_t for the root disk, complain and
	don't proceed to boot with an invalid boot device.

5d3d992565 Fill in the bi_bios_dev field in the bootinfo struct; the loader doesn't 
guess this value well in anything other than the simplest of situations.

461b36ab54 Update userref handling after discussion with submitter of previous 
patch.  lf can't be dereferenced after the unload attempt, in case it
was freed.  Instead, decrement first and back it out if the unload failed.
This should be relatively immune to races caused by the user since the
userref count will be zero for the duration of the actual unloading and
will stop further kldunload attempts.

2008c8087c Multicast code isn't quite correct. The RealTek wants the upper six bits 
of the CRC as the multicast hash table bit, not the lower six bits. Plus
we have to flip on all bits in the table for multicast mode.

8ab2fa0073 Gutted softdep_deallocate_dependencies and replaced it with a panic. It 
turns out to not be useful to unwind the dependencies and continue in
the face of a fatal error.
Also changed the log() to a printf() in softdep_error() so that it will
be output in the case of a impending panic.

33ce4218c6 Don't throw away the buffer contents on a fatal write error; just mark 
the buffer as still being dirty. This isn't a perfect solution, but
throwing away the buffer contents will often result in filesystem
corruption and this solution will at least correctly deal with transient
errors.
