5a3e77d851 Fixed overflow in the calculation of the number of inodes per group
for filesystems with almost the maximum number of sectors.  The maxiumum
is 2^31, but overflow is common for that size, and overflow normally
occurred here at size (2^31 - 4096).

90e05a748a Don't create superblocks with size larger than SBSIZE (8192). The
size was rounded up to a multiple of the fragment size, but this
gave invalid file systems when the fragment size was > SBSIZE (fsck
aborts early on them).  Now a fragment size of 32768 seems to work
(too-simple tests with fsck and iozone worked).

079709dc3a Some tweaks to get this to cope with ELF where the address space starts
higher up in memory (0x0800000 upwards) rather than near zero (0x1000
for our qmagic a.out format).  The method that mount_mfs uses to allocate
the memory within data size rlimits for the ram disk is entirely too much
of a kludge for my liking.  I mean, if it's run as root, surely it makes
sense to just raise the resource limits to infinity or something, and if
it's a non-root user mount (do these work? with mfs?) it could just fail
if it's outside limits.

28596d2346 Removed "hack to prevent overflow of a 32bit block number". Lite2 has a
better hack in ffs_vfsops.c.  The hack here restricted the maximum file
size to 2^39 bytes (512GB).  fs_bsize * 2^31 - 1 (16TB for the default
blocksize of 8K) would have been better.  There is no good way to remove
this limit on old BSD4.4 file systems.

dc6f8d1bd5 Allow use of the name "swap" instead of an actual swap device.
This makes configuration of mfs /tmp on diskless clients more intuitive
for people like me, that have used this feature on NetBSD and SunOS.
Using the -T option and /dev/null, while already supported,
is neither intuitive nor documented in the handbook.

4af9705ceb Fix the mount_mfs case from the last cleanup. The code was (ab)using
it's internal malloc() implementation to try and avoid overstepping it's
resource limits (yuk!).  Remain using libc's malloc(), but check the
resource limits right before trying to malloc the ramdisk space and leave
some spare memory for libc.  In Andrey's words, the internal malloc
was "true evil"..  Among it's sins is it's ability to allocate less memory
than asked for and still return success.  stdio would just love that. :-)

  - Removed flag arguments of '0' (required by POSIX).
  - Fixed code which expected an error return of 0.
  - Fixed code which thought any address with the high bit set
    was an error.
  - Check for failure where no checks were present.

7cb29d3394 This update adds the support for != 512 byte sector SCSI devices to
the sd & od drivers. There is also slight changes to fdisk & newfs
in order to comply with different sectorsizes.
Currently sectors of size 512, 1024 & 2048 are supported, the only
restriction beeing in fdisk, which hunts for the sectorsize of
the device.
This is based on patches to od.c and the other system files by
John Gumb & Barry Scott, minor changes and the sd.c patches by
me.
There also exist some patches for the msdos filesys code, but I
havn't been able to test those (yet).

e7bf085313 Yank out the rewriting of disklabels. This code can and will get confused
in a couple of cases, and it doesn't do much anyway.  It used to save only
the newfs params (block/frag/cgroup.. and nothing more.  Something that
don't belong in a disklabel in the first place.

55abc5794a Change the defaults for newfs to disregard the geometry in the disklabel.
We pretend we have one head with two megabyte worth of sectors per cylinder.

The code try to access another head in what it belives to the same
physical cylinder, because it belives that it would be faster than
waiting for the next free sector under this head to come around.

Most modern drives doesn't have a "classical" geometry, and thus
we end up fooling ourselves doing the above optimization.  With this
change we will fill a cylinder sequentially if we can, and thus get
much more mileage from the track-buffer/cache built into the drives.

As a result a lot of seeks to the next or previous track should be
avoided by this.

(My disk is a lot less noisy actually...)

You can still get the old behaviour, by specifying zero for the
numbers.

This will also solve the problem with newfs barfing at really big
drives.

3fa88dec7f Add support for filesystem-specific `-o' options, and re-implement the
most common cd9660 and nfs options like God intended them.  (It is now
possible to say

	mount -o ro,soft,bg,intr there:/foo/bar /foo/bar

again.)  This whole getmntopt() business is an incredible botch;
it never should have been anything more than a wrapper around
getsubopt(3).  Because if the way the current hackaround is implemented,
options which take arguments (like the old `rsize' and `wsize') are still
unavailable, and must be accessed the new, broken way.

(It's unimaginable how Berkeley managed to screw up one of the few things
about NFS that Sun actually got right to begin with!)

7ce005d7c1 1) If nrpos <= 1, don't output rpos table (and set fs_cpc to 0) - disabling
the use of the rotational position table.
2) Allow specification of 0 rotational positions (disables function).
3) Make rotdelay=0 and nrpos=0 by default.

   The purpose of the above is to optimize for modern SCSI (and IDE) drives
that do read-ahead/write-behind.
