949982f2a4 In calculating the f_bavail field, don't take 32 bit quantities and 
multiply them by 90 (to be divided by 100) and expect them to be sane
for very large values (I was getting a negative 'avail' count).

acffafa288 Oops, I messed up the lock. Reverting it until I have time to fix it, 
to avoid people getting trouble after the supscan hits.

b362aa16be Put lock around inode hashing, because getnewvnode or MALLOC might block, 
creating race conditions.

8c0a9bab00 Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many 
architectures), truncate them intelligently instead.
The truncation is done centralized in vnode_pager.c.
This prevents from wrap-over effects when parts of large (>2^32 byte) files
are mmapped.
Don't allow to mmap above the numerical range of vm_offset_t.
This is considered a temporary solution until the vm system handles the
object sizes/offsets more cleanly.

76c414a957 Add support for ext2fs, this needed a few modifications to ufs/ufs/inode.h: 
- added an "union inode_ext" to struct inode, for the per-fs extentions.
  For now only ext2fs uses it.
- i_din is now an union:
	union {
		struct  dinode ffs_din; /* 128 bytes of the on-disk dinode. */
		struct ext2fs_dinode e2fs_din; /* 128 bytes of the on-disk dinode. */
	} i_din
  Added a lot of #define i_ffs_* and i_e2fs_* to access the fields.
- Added two macros: FFS_ITIMES and EXT2FS_ITIMES. ITIMES calls the rigth
  macro, depending on the time of the inode. ITIMES is used where necessary,
  FFS_ITIMES and EXT2FS_ITIMES in other places.

66c4e32b11 Just increment the generation count. Using the time is bogus and defeats 
fsirand(8).

90688fce27 Change the second and third args to struct vfsops' (*vfs_mount)() to 
'const char *', and 'void *', respectively.  The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions.  The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...

34e2fb3bb6 Performance enhancement from Kirk McKusick <mckusick@McKusick.COM>: 
When freeing an indirect block, there is no need to write it (synchronously,
no less!) before tossing it.
