the system would panic when a user's inode quota was exceeded (see
PR 18959 for details). This fixes that problem.

check to see if it has been committed to disk. If it has never
been written, it can be freed immediately. For short lived files
this change allows the same inode to be reused repeatedly.
Similarly, when upgrading a fragment to a larger size, if it
has never been claimed by an inode on disk, it too can be freed
immediately making it available for reuse often in the next slowly
growing block of the same file.
Rewrote intro at top of file to reflect my better understanding of how it
the memory mapping works.
Clear the DONE list and move some thoughts into the TODO list.
Remove RECERR from RAY_DEBUG
Start to use a desired network parameter structure, only used in download
code as I've realised that there are some problems with the idea.
Break up ray_rx, and move the data packet handler into a seperate function. This meant some knock on changes in ray_rx_mgt/ray_rx_ctl to do with
mbuf freeing.
Remove some debug code/XXX comments that are out of date.
Force alphas to prefer mem mapping as the default.
Basically, we have a pointer to a function which we can call which will
return us a pointer to firmware for the card we have. We call this function
(if it's non-NULL) with the address of our mdvec f/w pointer.
The way this works is that if ispfw (as a module or a static) is loaded,
it initializes the pointer in isp_pci, so we can call into to it to fetch
a pointer to a f/w set.
If ispfw is MOD_UNLOADed, it's retained a pointer to our mdvec f/w pointers,
which then get zeroed out so we don't have any references to data that's
now gone from kernel memory. Removing the f/w saves ~360KBytes.
Alas, there is no autounload mechanism that works for is here.
This should allow one to load oldcard or newcard for testing. Please
let me know if this doesn't work. Don't load this and either of pcic
or pccard. I've not tried it, but I suspect bad things will happen.
incomplete, but will eventually allow the same drivers to function
with both oldcard and newcard.
o Remove include of opt_bus.h. It isn't needed and gets in the way of
module building.
through, establish what our LUN width is. Unfortunately, we can't ask
the f/w. If we loaded the f/w, we'll now assume we have expanded LUNs
(SCCLUN for fibre channel, just plain 32 LUN for SCSI). If we didn't
load firmware, assume 8 LUNs for SCSI and 1 LUN for Fibre Channel. We
have to assume only one LUN for Fibre Channel because the LUN setting
in Request Queue entries is in different places whether we have SCCLUN
firmware or not, so the only LUN guaranteed to work for both is LUN 0.
Clean up the rest of isp.c so that ISP2100_SCCLUN defines aren't used-
instead use run time determinants based upon isp->isp_maxluns.
After starting firmware, delay 500us to give it a chance to get rolling.
Fix the interrupt service routine to check for both isr && sema being zero
before thinking this was a spurious interrupt. Following the manuals,
allow for both Mailbox as well as Queue Reponse type interrupts for regular
SCSI.
(we always support fabric now). Remove SCCLUN definition (we always
support SCCLUN now, if we load the f/w). Add typedef definition of an
external firmware fetch function.
fields, not lex/yacc grammar so it is not an exact match but should be
close enough for most cases.
Deal with 'port?', 'irq?' style specifications. These are parsed as
seperate values in lex/yacc in config(8) but tripped up this helper tool.
deal with filename arguments. It is amazing how much you forget over time.
Thanks to the people that reminded me this. I knew there was an easy way
that didn't involve messing with $argv, filehandles, etc, but just could
not remember - all of my books are on the opposite side of the planet..
world as was our old way, rather than when building a kernel.
Some people do not like the new way, and the release building still assumes
modules are built with the world.
theory, this should allow the K7V Athlon motherboard to boot ok with boot
virus protection enabled. However, I have no hardware to test this. It
shouldn't break anything though. :)

address on an interface. This basically allows you to do what my
little setmac module/utility does via ifconfig. This involves the
following changes:
socket.h: define SIOCSIFLLADDR
if.c: add support for SIOCSIFLLADDR, which resets the values in
the arpcom struct and sockaddr_dl for the specified interface.
Note that if the interface is already up, we need to down/up
it in order to program the underlying hardware's receive filter.
ifconfig.c: add lladdr command
ifconfig.8: document lladdr command
You can now force the MAC address on any ethernet interface to be
whatever you want. (The change is not sticky across reboots of course:
we don't actually reprogram the EEPROM or anything.) Actually, you
can reprogram the MAC address on other kinds of interfaces too; this
shouldn't be ethernet-specific (though at the moment it's limited to
6 bytes of address data).
Nobody ran up to me and said "this is the politically correct way to
do this!" so I don't want to hear any complaints from people who think
I could have done it more elegantly. Consider yourselves lucky I didn't
do it by having ifconfig tread all over /dev/kmem.
