call with F_FSCTL set and F_SETFL calls generate calls to a new
fileop fo_fcntl. Add genfs_fcntl() and soo_fcntl() which return 0
for F_SETFL and EOPNOTSUPP otherwise. Have all leaf filesystems
use genfs_fcntl().

equivalent to a "block" is in FFS. Fixes vnds on MSDOSFS, and should
eliminate a 'getblk: block size invariant failed' panic.
Directly from PR7380 <elric@imrryr.org>.
* in the read vnode operator, check for IO_SYNC being set in the ioflag and
synchronously update the file's meta-data if appropriate.
* in the write vnode operator, update the appropriate checks for IO_SYNC being
set in the ioflag to reflect that IO_DSYNC is now inclusive-or'ed into
IO_SYNC, and require all IO_SYNC bits to be set for operations defined by
synchronized I/O file integrity completion but not by synchronized I/O data
integrity completion.
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code. i provided some help
getting swap and paging working, and other bug fixes/ideas. chuck
silvers <chuq@chuq.com> also provided some other fixes.
this is the rest of the MI portion changes.
this will be KNF'd shortly. :-)
PR4394: be more consistent with other MSDOSFS_DEBUG messages
PR4395: fix generation numbers as in the PR, and fix short name for e.g. x.aaaa
PR4396: easier fix then given in the PR
All PRs by Rick Byers. Thanks Rick for pointing these out
Don't panic if renaming a file to itself
Don't try to keep access times, there is no place for them
While being here, fix some minor bugs with VFAT handling
