c60e896954 undo the part of the last revision that made user block device access 
use the UBC interfaces.  too many problems with that yet.

13e5178e3d Don't hold vp->v_interlock when calling vcount(); vcount() calls 
vgone(), which may sleep.

7a615b0018 Remove usecount check in spec_open. It fails to catch VALIAS situations 
and vfs_mountedon will handle them all correctly.

db4108490a Adapt for VOP_FSYNC parameter change. 2000-09-19 22:01:59 +00:00

b0fb24279c change the lf_advlock() arguments from 
int     lf_advlock __P((struct lockf **,
           off_t, caddr_t, int, struct flock *, int));
to

int     lf_advlock __P((struct vop_advlock_args *, struct lockf **, off_t));

This matches common usage and is also compatible with similar change
in FreeBSD (though they use u_quad_t as last arg).

0b1963121a Add Kirk McKusick's soft updates code to the trunk. Not enabled by 
default, as the copyright on the main file (ffs_softdep.c) is such
that is has been put into gnusrc. options SOFTDEP will pull this
in. This code also contains the trickle syncer.

Bump version number to 1.4O

e682a080e9 In spec_close(), if we're not doing a non-blocking close and VXLOCK is 
not set, unlock the vnode before calling the device's close routine and
relock it after it returns. tty close routines will sleep waiting for
buffers to drain, which won't happen often times as the other side needs
to grab the vnode lock first.

Make all unmount routines lock the device vnode before calling VOP_CLOSE().

e1b25b7bd6 Make spec_write() process errors and return them, otherwise we don't even 
notice things like hitting the end of a partition or device.  (To be sure,
writes to block special files are rare, but as long as we support them...)

651b44e211 Rework the way kernel include files are installed. In the new method, 
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.

e9d17d38b5 avoid unnecessary aging of buffers. This used to make sense, when buffer 
caches were much smaller, but makes little sense now, and will become more
useless as RAM (and buffer cache) sizes grow.  Suggested by Bob Baron.
