as having flag SF_ARCHIVED on; this is wrong for directories, which don't
have any mode flags on msdosfs, so it's always treated as archived,
which leads to problems described in pr #8439. The semantics of the
archive flag differs between Unix and msdos/windoze, so it's better
to not set the flag at all even for regular files, to avoid surprises.
This fixes bin/8439 by Thomas Klausner.

differently here - we avoid changing correct code and only touch

This matches common usage and is also compatible with similar change
in FreeBSD (though they use u_quad_t as last arg).
a set of flags ("flags"). Two flags are defined, UPDATE_WAIT and
UPDATE_DIROP.
Under the old semantics, VOP_UPDATE would block if waitfor were set,
under the assumption that directory operations should be done
synchronously. At least LFS and FFS+softdep do not make this
assumption; FFS+softdep got around the problem by enclosing all relevant
calls to VOP_UPDATE in a "if(!DOINGSOFTDEP(vp))", while LFS simply
ignored waitfor, one of the reasons why NFS-serving an LFS filesystem
did not work properly.
Under the new semantics, the UPDATE_DIROP flag is a hint to the
fs-specific update routine that the call comes from a dirop routine, and
should be wait for, or not, accordingly.
Closes PR#8996.

differs a bit.
for end cluster, instead of explicitly passing 0xffff. This fixes potential
problem for FAT32, where cluster number may be legally bigger than 0xffff.
Also change clusteralloc() so that fillwith is not explicitly passed by caller
anymore (there is no need to use anything other than CLUST_EOFE).

It's shape is a bit different now than it was in rev 1.12, but is functionally

typically those allocated in respective filesystem's init function.
Needed so those filesystems which went in via LKM have a chance to
clean after themselves before unloading. This fixes random panics
when LKM for filesystem using pools was loaded and unloaded several
times.
For each leaf filesystem, add appropriate vfs_done routine.
