8b661a6175 This code got moved as a result of confusion between union mounts and
unionfs.  Julian has already revived the union mount part of this move
in vfs_syscalls.c rev 1.119, but forgot to take it out of here.

Add d_parms() to {c,b}devsw[].  If non-NULL this function points to
    a device routine that will properly fill in the specinfo structure.
    vfs_subr.c's checkalias() supplies appropriate defaults.  This change
    should be fully backwards compatible with existing devices.

98732ec693 Remove MAP_ENTRY_IS_A_MAP 'share' maps. These maps were once used to
attempt to optimize forks but were essentially given-up on due to
    problems and replaced with an explicit dup of the vm_map_entry structure.
    Prior to the removal, they were entirely unused.

df24433bbe This is a rather large commit that encompasses the new swapper,
changes to the VM system to support the new swapper, VM bug
    fixes, several VM optimizations, and some additional revamping of the
    VM code.  The specific bug fixes will be documented with additional
    forced commits.  This commit is somewhat rough in regards to code
    cleanup issues.

1c3fe295c3 A partial implementation of the procfs cmdline pseudo-file. This
is enough to satisfy things like StarOffice.  This is a hack, but doing
it properly would be a LOT of work, and would require extensive grovelling
around in the user address space to find the argv[].

982e80577d Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

e170b2ba75 Removed statically configured mount type numbers (MOUNT_*) and all
references to them.

The change a couple of days ago to ignore these numbers in statically
configured vfsconf structs was slightly premature because the cd9660,
cfs, devfs, ext2fs, nfs vfs's still used MOUNT_* instead of the number
in their vfsconf struct.

4630814c8b Add a new vnode op, VOP_FREEBLKS(), which filesystems can use to inform
device drivers about sectors no longer in use.

Device-drivers receive the call through d_strategy, if they have
D_CANFREE in d_flags.

This allows flash based devices to erase the sectors and avoid
pointlessly carrying them around in compactions.

c0cb9588c8 Quick fix for type mismatches which were fatal if longs aren't 32
bits.  We used a private, wrong, version of `struct dirent' to help
break getdirentries(), and we use a silly check that the size of this
struct is a power of 2 to help break mount() if getdirentries() would
not work.  This fix just changes the struct to match `struct dirent'
(except for the name length).

04d286f647 DEVFS completely bypasses the cdevsw and bdevsw tables now.
Each devfs node has (and has had fro a while) a pointer directly to
the correct cdefsw entry so just use it instead of doing the lookup.

There are several other places in the kernel that still use the tables
however, so they can't go away yet..

0262543b5f There is no such thing any more as "struct bdevsw".
There is only cdevsw (which should be renamed in a later edit to deventry
or something). cdevsw contains the union of what were in both bdevsw an
cdevsw entries.  The bdevsw[] table stiff exists and is a second pointer
to the cdevsw entry of the device. it's major is in d_bmaj rather than
d_maj. some cleanup still to happen (e.g. dsopen now gets two pointers
to the same cdevsw struct instead of one to a bdevsw and one to a cdevsw).

rawread()/rawwrite() went away as part of this though it's not strictly
the same  patch, just that it involves all the same lines in the drivers.

cdroms no longer have write() entries (they did have rawwrite (?)).
tapes no longer have support for bdev operations.
