Notes on my latest updates to -current:

Inclusion of Godmar Back's EXT2FS code.  Note that this code has
been modified by the FreeBSD team, so bugs should come here first.
We'll get the bug reports (and fixes) back to him and also eventually support
inclusion of the FreeBSD changes into his code base if he wants to.
It appears that the code works, so feel free to test it, but still be
gentle!!!

Soon (in the next few days), I'll commit the fsck and mkfs code for EXT2FS.

Hopefully a fix to the msync problem that is probably making mmaped
files not work very will especially in the case of INND problems and
NFS.  Thanks to Ron Minnich for pointing out at least one of the major
problems (it was simply just completely broken on NFS!!!.)  Please check
this out, and if it doesn't work -- I'll work on it again and again!!!  In
conjunction with the bug fix, the msync code has been cleaned up substantially.

MNT_ASYNC now means even more on UFS.  More of the meta-data is written
asynchronously and the VREG data is now written asynchronously.  I think
that even more can be done relatively safely.  This can really help on
bulk file restores or perhaps news spool partitions.
