I noticed recently that my CONFIG_CRYPTO_MD5 turned into a y again instead
of m. It turns out that CONFIG_NFSD_V4 is selecting it to be y even though
I've chosen to compile nfsd as a module.
In general when we have a bool sitting under a tristate it is better to
select things you need from the tristate rather than the bool since that
allows the things you select to be modules.
The following patch does it for nfsd.

Currently to turn on debug mode "user" has to edit ~10 files, to turn off he
has to do it again.
This patch introduce such changes:
1)turn on(off) debug messages via ".config"
2)remove unnecessary duplication of code
3)make "UFSD" macros more similar to function
4)fix some compiler warnings

The following series of patches introduces a kernel API for inotify,
making it possible for kernel modules to benefit from inotify's
mechanism for watching inodes. With these patches, inotify will
maintain for each caller a list of watches (via an embedded struct
inotify_watch), where each inotify_watch is associated with a
corresponding struct inode. The caller registers an event handler and
specifies for which filesystem events their event handler should be
called per inotify_watch.

This attached patches provide xattr support including POSIX-ACL and
SELinux support on JFFS2 (version.5).
There are some significant differences from previous version posted
at last December.
The biggest change is addition of EBS(Erase Block Summary) support.
Currently, both kernel and usermode utility (sumtool) can recognize
xattr nodes which have JFFS2_NODETYPE_XATTR/_XREF nodetype.
In addition, some bugs are fixed.
- A potential race condition was fixed.
- Unexpected fail when updating a xattr by same name/value pair was fixed.
- A bug when removing xattr name/value pair was fixed.
The fundamental structures (such as using two new nodetypes and exclusion
mechanism by rwsem) are unchanged. But most of implementation were reviewed
and updated if necessary.
Espacially, we had to change several internal implementations related to
load_xattr_datum() to avoid a potential race condition.

Everybody seems to be using /proc/vmcore as a method to access the kernel
crash dump. Hence probably it makes sense to enable CONFIG_PROC_VMCORE by
default if CONFIG_CRASH_DUMP is selected. This makes kdump configuration
further easier for a user.

OpenBSD doesn't see "." correctly in directories created by Linux. Copying
files over several KB will buy you infinite loop in __getblk_slow().
Copying files smaller than 1 KB seems to be OK. Sometimes files will be
filled with zeros. Sometimes incorrectly copied file will reappear after
next file with truncated size.

I have heard some complaints about people not finding CONFIG_CRASH_DUMP
option and also some objections about its dependency on CONFIG_EMBEDDED.
The following patch ends that dependency. I thought of hiding it under
CONFIG_KEXEC, but CONFIG_PHYSICAL_START could also be used for some reasons
other than kexec/kdump and hence left it visible. I will also update the
documentation accordingly.
o Following patch removes the config dependency of CONFIG_PHYSICAL_START
on CONFIG_EMBEDDED. The reason being CONFIG_CRASH_DUMP option for
kdump needs CONFIG_PHYSICAL_START which makes CONFIG_CRASH_DUMP depend
on CONFIG_EMBEDDED. It is not always obvious for kdump users to choose
CONFIG_EMBEDDED.
o It also shifts the palce where this option appears, to make it closer
to kexec and kdump options.
