1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

87241caa43 This commit is the embodiment of some VFS read clustering improvements.
Firstly, now our read-ahead clustering is on a file descriptor basis and not
on a per-vnode basis.  This will allow multiple processes reading the
same file to take advantage of read-ahead clustering.  Secondly, there
previously was a problem with large reads still using the ramp-up
algorithm.  Of course, that was bogus, and now we read the entire
"chunk" off of the disk in one operation.   The read-ahead clustering
algorithm should use less CPU than the previous also (I hope :-)).

171ed8bf14 Fixed lookup of ".." in checkpath. It always failed, so renames of
directories to a different parent directory always failed.  This bug
was caused by 4.4Lite2 changing the directory format and ext2fs not
keeping up.

Should be in 2.2.

f886b4857a Removed gratuitous differences between ext2_readwrite.c and ufs_readwrite.c.
This fixes several bugs and one missing feature:
- cluster_read() was needlessly used for reading files of size exactly 1
  block.
- EFAULT errors for read didn't terminate the loop.  This was probably
  harmless.
- IO_VMIO handling was missing near line 275.  I don't know what this does.
- B_CLUSTEROK was only set if (doclusterwrite) nead line 293.  This was
  harmless, if only because another bug prevents doclusterwrite from being
  0.
- MNT_NOATIME wasn't implemented.

This should be in 2.2, of course.

62c3734cbe Updated #includes to 4.4lite style. 1996-10-15 19:22:46 +00:00
Bruce Evans
ebedb5ad97 Cleaned up all headers that include <sys/ioctl.h> or <sys/ioccom.h>:
- don't include <sys/ioctl.h> in any header.  Include <sys/ioccom.h>
  instead.  This was already done in 4.4Lite for the most important
  ioctl headers.  Header spam currently increases kernel build
  times by 10-20%.  There are more than 30000 #includes (not counting
  duplicates) for compiling LINT.
- include <sys/types.h> if and only it is necessary to make the header
  almost self-sufficient (some ioctl headers still need structs from
  elsewhere).
- uniformized idempotency ifdefs.  Copied the style in the 4.4Lite
  ioctl headers.

1996-09-20 05:51:12 +00:00
Nate Williams
030e2e9ebb In sys/time.h, struct timespec is defined as:
/*
         * Structure defined by POSIX.4 to be like a timeval.
         */
        struct timespec {
                time_t  ts_sec;         /* seconds */
                long    ts_nsec;        /* and nanoseconds */
        };

        The correct names of the fields are tv_sec and tv_nsec.

9b2b0822b7 Removed unused #includes of <i386/isa/icu.h> and <i386/isa/icu.h>. icu.h
is only used by the icu support modules and by a few drivers that know
too much about the icu (most only use it to convert `n' to `IRQn').  isa.h
is only used by ioconf.c and by a few drivers that know too much about
isa addresses (a few have to, because config is deficient).

Numerous fixes to the size of objects allocated for files.  Additionally,

Fixes for proper positioning of vnode_pager_setsize in msdosfs and ext2fs.
Fixes in the swap pager for exhausted resources.  The pageout code
	will not as readily thrash.
Change the page queue flags (PG_ACTIVE, PG_INACTIVE, PG_FREE, PG_CACHE) into
	page queue indices (PQ_ACTIVE, PQ_INACTIVE, PQ_FREE, PQ_CACHE),
	thereby improving efficiency of several routines.
Eliminate even more unnecessary vm_page_protect operations.
Significantly speed up process forks.
Make vm_object_page_clean more efficient, thereby eliminating the pause
	that happens every 30seconds.

81ab2caf0a Replaced nxreset by noreset (if the reset function gets called, then the
device must be configured.  It's hard to tell whether a reset function
should be noreset or nullreset since reset functions are never called.
Most drivers use nullreset but noreset has the advantage of complaining
if somehow gets called).

87f6c6625d Pass 3 of the great devsw changes
most devsw referenced functions are now static, as they are
in the same file as their devsw structure. I've also added DEVFS
support for nearly every device in the system, however
many of the devices have 'incorrect' names under DEVFS
because I couldn't quickly work out the correct naming conventions.
(but devfs won't be coming on line for a month or so anyhow so that doesn't
matter)

If you "OWN" a device which would normally have an entry in /dev
then search for the devfs_add_devsw() entries and munge to make them right..
check out similar devices to see what I might have done in them in you
can't see what's going on..
for a laugh compare conf.c conf.h defore and after... :)
I have not doen DEVFS entries for any DISKSLICE devices yet as that will be
a much more complicated job.. (pass 5 :)

pass 4 will be to make the devsw tables of type (cdevsw * )
rather than (cdevsw)
seems to work here..
complaints to the usual places.. :)

53ac6efbd8 OK, that's it..
That's EVERY SINGLE driver that has an entry in conf.c..
my next trick will be to define cdevsw[] and bdevsw[]
as empty arrays and remove all those DAMNED defines as well..

Each of these drivers has a SYSINIT linker set entry
that comes in very early.. and asks teh driver to add it's own
entry to the two devsw[] tables.

some slight reworking of the commits from yesterday (added the SYSINIT
stuff and some usually wrong but token DEVFS entries to all these
devices.

BTW does anyone know where the 'ata' entries in conf.c actually reside?
seems we don't actually have a 'ataopen() etc...

If you want to add a new device in conf.c
please  make sure I know
so I can keep it up to date too..

as before, this is all dependent on #if defined(JREMOD)
(and #ifdef DEVFS in parts)
