replaced by a function long ago..

From NetBSD;

checks if the mount is actually interrutable, and if not sets it 0.
remove this argument from nfs_vinvalbuf and just do the checking inside
the function.
o give nfs_vinvalbuf() a makeover so it looks nice. (spacing, casts, &c);
o Actually pass PCATCH too tsleep() if the mount it interrutable.
ok art@, blambert@
|
|
and the dead code that was supposed todo that has been removed.
o rename the NFS_SMALLFH constant to NFS_MAXFHSIZE, since it better
reflects what it's for.

nfs_iodwant array became unused. Garbage collect and free up
a few bytes.
ok thib@

as it was never used because there were 64-bit buffers already allocated
for filehandles in nfsnode structs.
ok thib@

wrong. But this was harmless anyway since sys_statfs() sets this field
corrently after calling VFS_STATFS();

them going negative - this consists of identifying a number of cases of
IO not going through the buffer cache and marking those buffers with
B_RAW - as well as fixing nfs_bio to show pending writes and reads through
the buffer cache via NFS
still has a problem with mishandling the counters I believe in the
async/sync fallback case where counters stay positive which will be
addressed seperately.

not just a return value, nfs_lookitup treats it specially when *npp
is not NULL.
- nfs_lookitup - When we match the file handle to the directory
filehandle (lookup on '.'), initialize np so that we don't return
stack garbage to the caller. The function shouldn't ever be
called with '.' at this moment, but that's no reason to not do the
right thing in case future callers use it that way.

a) we're attempting to wake a specific process which
b) sleeps on a unique address
which means that there's no need to continue traversing the sleep
queue once the process has been found and awakened.

mbuf that points to the rest of the chain (if it is a
chain).
ok blambert@

wasted hours tracking down a phantom mbuf leak.
ok thib@
|

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

filehandle -> mbuf write macros.
Removes `magic' variable cp which was used only in these macros,
and should lead to marginally better mbuf packing as well.
`slap it in' thib@

the accidental situation that used to happen when it leaked buffers and allowed
the syncer to do it, however this puts a limit on how much of the buffer cache
it is allowed to consume to a sensible amount - improves nfs write performance
since we don't have to do tons of them synch now.
Modifies the existing code to use wakeup_one instead of cruft, and now
all nfsiod's tsleep the same way.

conversions that should shave a few bytes off the kernel.

contents of this file inside #ifdef _KERNEL; there's nothing here that
userland should ever need/touch.
but then again, some userland programs define _KERNEL before they include
kernel header files *shrugh*...

depends on them being set. This should be the removal of the original
return-to-userland-to-authenticate code that was apparently an unfinished
experiment.

Rescue nfsm_reqhead macro name and rename nfsm_reqh.
End of one-liners from nfsm_subs.h.

to support authentication other than AUTH_UNIX will replace this
with a (hopefully) much better system.

the function it was named after took 4 arguments instead of 2.

NFS mbufs, mbufs now contain all their internal buffer state internally,
the way god intended.

you need to upgrade nfsstat and the relevant header files

is kinda silly. Don't.
Prettify a bit in the process.

the buf due too all of the nfs iod's being busy; this downgrades
the write to a sync one and allows to handle this.
ok art@, beck@

file copies to nfsv2 causes the system to eventually peg the console.
On the console ^T indicates that the load is increasing rapidly, ddb
indicates many calls to getbuf, there is some very slow nfs traffic
making none (or extremely slow) progress. Eventually some machines
seize up entirely.

Also, it is historical practice to #include <sys/queue.h>
when using queue.h macros.

earlier commit for some reason did not go through

add a function to handle cache_enter()'s for us since
we need to update the appropriate timestamps so we don't
miss on lookup;
o Do not purge the dvp in nfs_rmdir(), since there's no need;
o cache the new entry created in nfs_mkdir();
o Do caching of the access modes, this drastically reduces the
amount of over the wire access RPCs we do in the NFSv3 case.
This diff was written by Pedro Martelletto, sometime in 2004.
A lot of people have been running with it at one time or another,
this includes at least markus and matthieu.

1) remove multiple size queues, introduced as a stopgap.
2) decouple pages containing data from their mappings
3) only keep buffers mapped when they actually have to be mapped
(right now, this is when buffers are B_BUSY)
4) New functions to make a buffer busy, and release the busy flag
(buf_acquire and buf_release)
5) Move high/low water marks and statistics counters into a structure
6) Add a sysctl to retrieve buffer cache statistics
Tested in several variants and beat upon by bob and art for a year. run
accidentally on henning's nfs server for a few months...
ok deraadt@, krw@, art@ - who promises to be around to deal with any fallout

the superuser. access(2) will now only indicate success for X_OK on
non-directories if there is at least one execute bit set on the file.
