[PATCH] Fix the sunrpc cache/reader management properly.
A recent patch changed the rpc/*/channel files to behave
differently depending on whether they were open for read or not.
This hadn't been tested thoroughly. The cache_reader structure
that was now only allocated when opening for read, had a field that
was iused when writing.
This patch removes that field and takes a different approach to solving
the issue it addressed.

[PATCH] spurious SIGCHLD from dying thread group leader
A dying initial thread (thread group leader) sends SIGCHLD when it exits,
but it ought to wait until all other threads exit as well. The cases of
secondary threads exitting first were handled properly, but not this one.
This exit.c patch fixes that test case, and I think catches the other
potential bugs of this kind as well. The signal.c change adds some bug
catchers, the second of which will trip on the test case in the absence
of the exit.c fix.

This patch moves the resource parsing functions from support.c to the

This patch greatly cleans up the code in both the parsing functions
and their connection with the pnpbios driver. Also note that
pnpbios.h has been added for local pnpbios functions.

[PATCH] nfsv4 page boundary handling fixes.
From: Galen Michael Elias <gme@citi.umich.edu>
This patch fixes two places where the handling of page boundaries was
incorrect and caused to IO_ERR's when it shouldn't have.
1. In decode_write it was just a small typo.
2. In decode_compound we avoid using READ_BUF, but don't provide all of
it's functionality, specifically crosses a page boundary.

[PATCH] Create a mountpoint for the nfsd filesystem.
Though the nfsd module can create this, having it always
there makes auto-loading-on-mount work better.
Note: it was previously recommended that the nfsd filesystem be mounted
on /proc/fs/nfs, which I was never comfortable with.
Henceforth the recommended location will be /proc/fs/nfsd.
nfs-utils 1.0.6 and later will support both.

Such a request would cause the nul terminator to be written

[PATCH] Make sure sunrpc/cache doesn't confuse writers with readers.
When a sunrpc/cache channel is not open for reading, the
cache doesn't bother making and waiting for up-calls.
However it doesn't currently distingish between open-for-read/write
and open-for-write, so an op-for-write will look like a reader
and will cause inappropriate waiting.
This patch checks if a file is open-for-read and will only register
a file as a reader if it really is one.

Make "static const" initializer to zero explicit, since truly
constant values should not end up in the BSS.
We're better off having the compiler put it in the .rodata
section (which it will, thanks to the initializer and the
"const"), since that will result in it being nicely cacheable
in shared SMP caches.

[ATM]: Minor LANAI fixes from mitch@sfgoth.com.
1. pci_device_id structures shouldn't be __devinitdata. Greg removed
all of the instances of this in the 2.6.0-test1 tree, but unforunately
my recent coversion of lanai.c introduced another one.
2. The lanai PCI id constants have now been merged into the kernel headers
so we don't need to define our own copies.
3. The ioctl's exported by lanai shouldn't be - they were intended for
debugging only, never for release. For now they're just '#if 0'ed out.
They're somewhat dangerous since they don't check any capabilities so
any user could DoS the interface.
