9504abaad7 Complete the separation of ext2fs from ufs by copying the remaining
shared code and converting all ufs references. Originally it may
have made sense to share common features between the two filesystems,
but recently it has only caused problems, the UFS2 work being the
final straw.

All UFS_* indirect calls are now direct calls to ext2_* functions,
and ext2fs-specific mount and inode structures have been introduced.

file with a in Lite1 before being cvs-added to FreeBSD.

a0595d0249 Add a flags parameter to VFS_VGET to pass through the desired
locking flags when acquiring a vnode. The immediate purpose is
to allow polling lock requests (LK_NOWAIT) needed by soft updates
to avoid deadlock when enlisting other processes to help with
the background cleanup. For the future it will allow the use of
shared locks for read access to vnodes. This change touches a
lot of files as it affects most filesystems within the system.
It has been well tested on FFS, loopback, and CD-ROM filesystems.
only lightly on the others, so if you find a problem there, please
let me (mckusick@mckusick.com) know.

7ef47eec4c ext2fs relies on UFS support code, and as a result also requires
extattr.h to be included.  This fixes the broken ext2fs build as of
the import of extattr code.

Also added $FreeBSD: $ to a couple of files that didn't have them,
without which I couldn't commit this fix.

de5d1ba57c Don't pass unused unused timestamp args to UFS_UPDATE() or waste
time initializing them.  This almost finishes centralizing (in-core)
timestamp updates in ufs_itimes().

4591d9bb7e UFS_UPDATE() takes a boolean `waitfor' arg, so don't pass it the value
MNT_WAIT when we mean boolean `true' or check for that value not being
passed.  There was no problem in practice because MNT_WAIT had the
magic value of 1.

9702cd0422 Fixed initialization of new inodes. ext2fs doesn't clear inodes when
they are deleted, so inodes must be cleared when they are reused, but
we didn't clear the indirect blocks.  This caused serious filesystem
corruption.

987f569678 Another VFS cleanup "kilo commit"
1.  Remove VOP_UPDATE, it is (also) an UFS/{FFS,LFS,EXT2FS,MFS}
    intereface function, and now lives in the ufsmount structure.

2.  Remove VOP_SEEK, it was unused.

3.  Add mode default vops:

    VOP_ADVLOCK          vop_einval
    VOP_CLOSE            vop_null
    VOP_FSYNC            vop_null
    VOP_IOCTL            vop_enotty
    VOP_MMAP             vop_einval
    VOP_OPEN             vop_null
    VOP_PATHCONF         vop_einval
    VOP_READLINK         vop_einval
    VOP_REALLOCBLKS      vop_eopnotsupp

    And remove identical functionality from filesystems

4.   Add vop_stdpathconf, which returns the canonical stuff.  Use
     it in the filesystems.  (XXX: It's probably wrong that specfs
     and fifofs sets this vop, shouldn't it come from the "host"
     filesystem, for instance ufs or cd9660 ?)

5.   Try to make system wide VOP functions have vop_* names.

6.   Initialize the um_* vectors in LFS.

(Recompile your LKMS!!!)

cec0f20ce7 VFS mega cleanup commit (x/N)
1.  Add new file "sys/kern/vfs_default.c" where default actions for
    VOPs go. Implement proper defaults for ABORTOP, BWRITE, LEASE,
    POLL, REVOKE and STRATEGY.  Various stuff spread over the entire
    tree belongs here.

2.  Change VOP_BLKATOFF to a normal function in cd9660.

3.  Kill VOP_BLKATOFF, VOP_TRUNCATE, VOP_VFREE, VOP_VALLOC.  These
    are private interface functions between UFS and the underlying
    storage manager layer (FFS/LFS/MFS/EXT2FS).  The functions now
    live in struct ufsmount instead.

4.  Remove a kludge of VOP_ functions in all filesystems, that did
    nothing but obscure the simplicity and break the expandability.
    If a filesystem doesn't implement VOP_FOO, it shouldn't have an
    entry for it in its vnops table.  The system will try to DTRT
    if it is not implemented.  There are still some cruft left, but
    the bulk of it is done.

5.  Fix another VCALL in vfs_cache.c (thanks Bruce!)

40715905a7 I think my previous change may have opened a race conditio.

34a6a33036 ufs_ihashrem() should not be called from the UFS layer, but from the
lower layer (LFS/FFS/?) like the rest of the ihash functions.
Otherwise it is impossible to make a lower layer that doesn't use the
ihash facility.

3c81694426 Fixed some invalid (non-atomic) accesses to `time', mostly ones of the
form `tv = time'.  Use a new function gettime().  The current version
just forces atomicicity without fixing precision or efficiency bugs.
Simplified some related valid accesses by using the central function.
