1. Establish a simple API for process freezing defined in linux/include/sched.h:
frozen(process) Check for frozen process
freezing(process) Check if a process is being frozen
freeze(process) Tell a process to freeze (go to refrigerator)
thaw_process(process) Restart process
frozen_process(process) Process is frozen now2. Remove all references to PF_FREEZE and PF_FROZEN from all
kernel sources except sched.h3. Fix numerous locations where try_to_freeze is manually done by a driver
4. Remove the argument that is no longer necessary from two function calls.
5. Some whitespace cleanup
6. Clear potential race in refrigerator (provides an open window of PF_FREEZE
cleared before setting PF_FROZEN, recalc_sigpending does not check
PF_FROZEN).This patch does not address the problem of freeze_processes() violating the rule
that a task may only modify its own flags by setting PF_FREEZE. This is not clean
in an SMP environment. freeze(process) is therefore not SMP safe!Signed-off-by: Christoph Lameter

o Adds support for parsing core ELF32 headers.
o I am expecting ELF32 support to go away down the line. This patch has been
introduced for testing purposes as gdb can not parse ELF64 headers for
i386. When a decent user space solution is available, ELF32 support
can go away.Signed-off-by: Vivek Goyal

From: "Vivek Goyal"
o Support for /proc/vmcore interface. This interface exports elf core image
either in ELF32 or ELF64 format, depending on the format in which elf headers
have been stored by crashed kernel.
o Added support for CONFIG_VMCORE config option.
o Removed the dependency on /proc/kcore.From: "Eric W. Biederman"
This patch has been refactored to more closely match the prevailing style in
the affected files. And to clearly indicate the dependency between
/proc/kcore and proc/vmcore.cFrom: Hariprasad Nellitheertha

This patch reworks filemap_xip.c with the goal to reduce code duplication
from mm/filemap.c. It applies agains 2.6.12-rc6-mm1. Instead of
implementing the aio functions, this one implements the synchronous
read/write functions only. For readv and writev, the generic fallback is
used. For aio, we rely on the application doing the fallback. Since our
"synchronous" function does memcpy immediately anyway, there is no
performance difference between using the fallbacks or implementing each
operation.Signed-off-by: Carsten Otte

- generic_file* file operations do no longer have a xip/non-xip split
- filemap_xip.c implements a new set of fops that require get_xip_page
aop to work proper. all new fops are exported GPL-only (don't like to
see whatever code use those except GPL modules)
- __xip_unmap now uses page_check_address, which is no longer static
in rmap.c, and defined in linux/rmap.h
- mm/filemap.h is now much more clean, plainly having just Linus'
inline funcs moved here from filemap.c
- fix includes in filemap_xip to make it build cleanly on i386Signed-off-by: Carsten Otte

NFSv4 clients are required to know what state they have on the server so that
they can reclaim it on server reboot. However, it is possible for
pathalogical combinations of server reboots and network partitions to leave a
client in a state where it cannot know whether it has lost its state on the
server.For this reason, rfc3530 requires that we store some information about clients
to stable storage.So we maintain a directory /var/lib/nfs/v4recovery with a subdirectory for
each client with active state. We leave open the possibility of including
files underneath each such subdirectory with information about the client, but
for now the subdirectories are empty.We create a client subdirectory whenever a client makes its first non-reclaim
open_confirm.We remove a client subdirectory whenever either
a) its lease expires, or
b) the grace period ends without it reclaiming anything.
When handling reclaims, we allow the reclaim if and only if the client doing
the reclaim has a subdirectory.This patch adds just the code to scan the recovery directory on nfsd startup.

The cb_parsed field is only used by probe_callback, to determine whether the
callback information has been filled in by setclientid. But there is no way
that probe_callback() can be called without that having already happened, so
that check is superfluous, as is cb_parsed.Signed-off-by: J. Bruce Fields

>From the language of rfc3530 section 8.1.3 (e.g., the suggestion that a
"process id" might be a reasonable lockowner value) it's conceivable that a
client might want to use the same lockowner string on multiple files, so we may
as well allow that. We expect each use of open_to_lockowner to create a
distinct seqid stream, though.For now we're also allowing multiple uses of open_to_lockowner with the same
open, though it seems unlikely clients would actually do that.Also add a comment reminding myself of some very non-scalable data structures.

Trivial renaming patch:
I can never remember, while looking at various lists relating the nfsd4 state
structures, which are the "heads" and which are items on other lists, or which
structures are actually on the various lists. The following convention helps
me: given structures foo and bar, with foo containing the head of a list of
bars, use "bars" for the name of the head of the list contained in the struct
foo, and use "per_foo" for the entries in the struct bars.Already done for struct nfs4_file; go ahead and do it for the other nfsd4
state structures.Signed-off-by: J. Bruce Fields

For the purposes of reboot recovery, we want to do some work during the
transition period at the end of the grace period. Some of that work must be
guaranteed to have a certain relationship with the end of the grace period, so
we want to control the transition there.Our approach is to modify the in_grace() checks to consult a global variable
instead of checking the time directly, to schedule the first run of the
laundromat thread at the end of the grace period, and to set the global
end-of-grace-period there.Signed-off-by: J. Bruce Fields

For the purposes of reboot recovery we keep a directory with subdirectories
each having a name that is the ascii hex representation of the md5 sum of a
client identifier for an active client.This adds the code to calculate that name. We also use it for the purposes of

are md5 collisions, then we'll return clid_inuse to the second.Signed-off-by: Andy Adamson

The only way the protocol gives to change the lease time on the fly is to
simulate a reboot. We don't have that completely right in the current code;
among other things, we should probably put lockd in grace too while we do
this.For now, let's just keep this simple, and wait till the next time nfsd starts
to register any changes in lease time. If the administrator really wants to
change the lease time *now*, they can go ahead and bring nfsd down and then
back up again after changing the lease time.Also remove the "if (reclaim_str_hashtbl_size == 0)" case, a shortcut which
skips the grace period if we know of no clients in need of recovery. This
isn't going to work well with nlm.Signed-off-by: J. Bruce Fields
