fvdl d040bd5908 Return error in the case of using ODIOCGDINFO or ODIOCGDEFLABEL when 
the number of partitions is > OLDMAXPARTITIONS. This is better
than silently truncating the label (don't want to silently throw
away partitions when using an old disklabel binary on a label with
> 8 partitions). From Enami Tsugutomo.

fvdl e2d1c1f926 Adapt all disk devices in MI directories to handle ODIOC* calls 
for ports that have bumped MAXPARTITIONS (and thus define
__HAVE_OLD_DISKLABEL).

enami 07702f68a6 Introduce new filesystem type FS_CCD so that an operator can mark the 
ccd component partition.  Note that the ccd driver still allows partitions
of any types as components since an on-disk BSD disklabel isn't available
on some port.

fvdl 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.

thorpej 0272b2ab8e Whole lotta cleanup wrt. how configuration data is stored internally, and 
just lockmgr(), not our home-grown locking functions.

thorpej d272bb0024 Handle the case where ccdbuffer() fails due to memory shortage. Build 
a fifo of component buffers, and free them if ccdbuffer() fails.  Once
all component buffers are build, run through the fifo and fire off the
requests to the components.

thorpej 00172c10d5 Nuke the mirroring code. RAIDframe is about to go in, and is a much 
better mirroring solution.

The ccd driver will stay, even in the presence of RAIDframe, for applications
where just RAID-0 is needed (much smaller code footprint).

kleink d72a3b2da1 Leftover from last commit: require us to be initialized when a DIOCGDINFO 
ioctl(2) is issued; the uninitialized disklabel pointer might get dereferenced
otherwise.

thorpej e06bb29b00 Two changes to ccdsize(): 
- If the partition was previously open, don't do the open/close steps.
  (Sync with other disk drivers.)
- foosize()'s return value is in DEV_BSIZE units; adjust the size obtained
  from the disklabel accordingly.

mycroft 8f8b0d91e5 Remove bogus use of splhigh(), and apparently unneeded bzero(). 1997-03-12 22:31:37 +00:00
thorpej 9a815ed696 A performance optimization, inspired by a conversation with Thor Simon: 
- Keep a freelist of component buffer headers, defaulting
	  to 8 headers per component (tunable with the CCDNBUF
	  kernel compile option).
	- When allocating a component buffer, try to pull a header
	  off the freelist first, falling back on MALLOC() if the
	  freelist is empty.  Use MALLOC() rather than malloc(),
	  because it will attempt to short-cut the allocation before
	  actually making a full-blown malloc() call.
	- Keep statistics on how many component buffer headers have
	  been allocated and how many of those allocations have
	  resulted in freelist misses.

With these changes, I observed measurable decreases in system and
wall clock time on operations on an 8G ccd, as well as a measurable
drop in the time spent in ccdbuffer() (measured with kernel profiling).
