* Rather than using mnt_maxsymlinklen to indicate that a file systems returns
d_type fields(!), add a new internal flag, IMNT_DTYPE.
Add 3 new elements to ufsmount:
* um_maxsymlinklen, replaces mnt_maxsymlinklen (which never should have existed
in the first place).
* um_dirblksiz, which tracks the current directory block size, eliminating the
FS-specific checks littered throughout the code. This may be used later to
make the block size variable.
* um_maxfilesize, which is the maximum file size, possibly adjusted lower due
to implementation issues.
Sync some bug fixes from FFS into ext2fs, particularly:
* ffs_lookup.c 1.21, 1.28, 1.33, 1.48
* ffs_inode.c 1.43, 1.44, 1.45, 1.66, 1.67
* ffs_vnops.c 1.84, 1.85, 1.86
Clean up some crappy pointer frobnication.
Move info about cylinders to the 'ask for units' menu.
(translations need checking, done by cutting sentences)
Stop i386 always asking for units.
Use BIOS cylinders for MBR and disk cylinders for the disklabel.
(code intended to do this, but got it wrong...)
Mark some menus as 'sub menu' or MC_SUBMENU so that the screen underneath
is saved.
Add GENERIC.MPACPI to i386 menu.
wdc_regs structure, and array of which (indexed per channel) is pointed
to by struct wdc_softc.
- Move the resulting wdc_channel structure to atavar.h and rename it to
ata_channel. Rename the corresponding flags.
- Add a "ch_ndrive" member to struct ata_channel, which indicates the
maximum number of drives that can be present on the channel. For now,
this is always 2. Add an ATA_MAXDRIVES constant that places an upper
limit on this value, also currently 2.

rarely in the normal case. (Note: This happens at reboot/shutdown time because
all file systems are unmounted.)
Also, for IN_MODIFY, use IN_ACCESSED, not IN_MODIFIED; otherwise "ls -l" of
your device node or FIFO would cause the time stamps to get written too
quickly.
setting those flags, it does not cause the inode to be written in the periodic
sync. This is used for writes to special files (devices and named pipes) and
FIFOs.
Do not preemptively sync updates to access times and modification times. They
are now updated in the inode only opportunistically, or when the file or device
is closed. (Really, it should be delayed beyond close, but this is enough to
help substantially with device nodes.)
And the most amusing part:
Trickle sync was broken on both FFS and ext2fs, in different ways. In FFS, the
periodic call to VFS_SYNC(MNT_LAZY) was still causing all file data to be
synced. In ext2fs, it was causing the metadata to *not* be synced. We now
only call VOP_UPDATE() on the node if we're doing MNT_LAZY. I've confirmed
that we do in fact trickle correctly now.
* Process A is closing one file descriptor belonging to a device. In doing so,
ffs_update() is called and starts writing a block synchronously. (Note: This
leaves the vnode locked. It also has other instances -- stdin, et al -- of
the same device open, so v_usecount is definitely non-zero.)
* Process B does a revoke() on the device. The revoke() has to wait for the
vnode to be unlocked because ffs_update() is still in progress.
* Process C tries to open() the device. It wedges in checkalias() repeatedly
calling vget() because it returns EBUSY immediately.
To fix, this:
* checkalias() now uses LK_SLEEPFAIL rather than LK_NOWAIT. Therefore it will
wait for the vnode to become unlocked, but it will recheck that it is on the
hash list, in case it was in the process of being revoke()d or was revoke()d
again before we were woken up.
* Since we're relying on the vnode lock to tell us that the vnode hasn't been
removed from the hash list *anyway*, I have moved the code to remove it into
the DOCLOSE section of vclean(), inside the vnode lock.
In the example at hand, process A was sh(1), process B was a child of init(8),
and process C was syslogd(8).

This addresses a long-held gripe on the part of a number of people,
including myself, which completely violated the POLS.
Bump version for this and previous pkg_admin modification.
Fixes the change request in PR 26583, but in a different manner,
preserving existing behaviour and making the new behaviour dependent
upon a command line option.
