ntfs_fill_super() and ntfs_read_inode_mount() cleaned up.  Removed
the kludges around the first iget() on NTFS.  Instead of playing with
(re)setting ->s_op we have the MFT_FILE inode set up by explicit new_inode()/
set ->i_ino/insert_inode_hash()/call ntfs_read_inode_mount() directly.
That kills the need of second super_operations and it allows to return
error from ntfs_read_inode_mount() without resorting to ugly "poisoning"
tricks.

Ok, well there aren't too many folks using an QLA2100 in a fabric
topology, if there were, they wouldn't have gotten very far in the
driver load sequence.  I've been able to scrape-up a QLA2100, 1Gig
switch, and an JBOD.  Upon loading the 8.00.00b12k driver, the
firmware successfully logs into the switch, the driver receives a
LOOP_UP event, but, the kernel panics due to NULL pointer dereference
while trying to perform an RFT_ID  -- the attached patch against
current scsi-misc-2.6 fixes that problem.

The patch to close all the open/close/hotplug races in sr left the
module refcounting broken so that the ULD housing the CD device now
can't be removed until the device itself is removed.

This patch (structurally identical to the one for sd.c to perform the
same function) fixes the module refcounting.

This fixes a situation where the handler can exit too early.

Set up SMT for the domain scheduler on x86-64.  This way the scheduling
works better on HyperThreading aware systems; in particular it will use
both physical CPUs before sharing two virtual CPUs on the same package. 
This improves performance considerably in some cases.

From: Rusty Russell <rusty@rustcorp.com.au>

PowerPC64 ABI has ".funcname" (the actual function) and "funcname" (the
function descriptor) and we strip off the dots in "dedotify" called from
module_frob_arch_sections().  We need to also de-dotify the corresponding
names in the __version section.

Actually has nothing to do with __down, it's just that we only print the
first symbol whose version is missing.

From: Paul Mackerras <paulus@samba.org>

It turns out that we are not handling the TABDLY bits of the termios
c_oflag field correctly on PPC, PPC64 and Alpha.  These three architectures
have a value for XTABS that is different from the TAB3 value.  POSIX
specifies that setting the TABDLY field to TAB3 should result in tabs being
expanded to spaces.  In n_tty.c:opost() we check for O_TABDLY(tty) ==
XTABS, which is fine on most architectures because they have XTABS == TAB3.

I think the right thing to do is just to change the definition of XTABS to
be the same as TAB3 on these architectures.  The patch below does this for
PPC and PPC64 (and I suggest the Alpha maintainer should do the same).  At
the moment, applications using either the XTABS or TAB3 values won't get
the expected behaviour.  With this patch, apps that use TAB3 will get the
expected behaviour.  Apps that use XTABS will need to be recompiled (but
note that the POSIX-specified name to use is TAB3 not XTABS).

    I would just like to say that I have no difficulties with intermezzo
    being rm -rf'd.  There are probably only a handful of users.  

    In the past 4 years nobody has supported InterMezzo sufficiently for
    it to become successful.  I have been fortunate to get really good support
    for the Lustre project.  So I have focussed on that.  Lustre 1.X has
    become really solid.

    The disconnected operation, caching and mirroring functionality of
    InterMezzo will become available in Lustre as a new feature in version 2. 

     So I see no point in keeping InterMezzo if it is a nuisance. 


The patch removes the references to intermezzo.  Please do a `bk rm' of
fs/intermezzo.

We may as well make usermodehelper_init() core_initcall as well, to make

We need to register the binfmts earlier, so normal initcalls can successfully

This patch addresses the longstanding problem wherein Oracle needs
CAP_IPC_LOCK to allocate SHM_HUGETLB shm memory, but people don't want to run
Oracle as root, and capabilties are busted.

Various ideas with rlimits didn't work out, mainly because these objects live
beyond the lifetime of the user processes which establish them.

What we do is to create root-writeable /proc/sys/vm/hugetlb_shm_group which
specifies a single group ID.  Users who belong to that group may allocate
hugepages for SHM_HUGETLB shm segments.

So the sysadmin will greate a new group, say `hugepageusers', will add the
oracle user to that group and will write that group's ID into
/proc/sys/vm/hugetlb_shm_group.

From: David Gibson <david@gibson.dropbear.id.au>

add_to_page_cache() locks the given page if and only if it suceeds.  The
hugepage code (every arch), however, does an unlock_page() after
add_to_page_cache() before checking the return code, which could trip the
BUG() in unlock_page() if add_to_page_cache() failed.

In practice we've never hit this bug, because the only ways
add_to_page_cache() can fail are when we fail to allocate a radix tree node
(very rare), or when there is already a page at that offset in the radix
tree, which never happens during prefault, obviously.  We should probably
fix it anyway, though.

The analagous bug in some of the patches floating about to
demand-allocation of hugepages is more of a problem, because multiple
processes can race to instantiate a particular page in the radix tree -
that's been hit at least once (which is how I found this).

Zhenmin's checker tool <zli4@cs.uiuc.edu> detected this:

 9. /drivers/pci/hotplug/shpchp_ctrl.c, Line 1575:
 err("%s: Failed to disable slot, error code(%d)\n", __FUNCTION__, rc);

 Maybe change to:
 err("%s: Failed to disable slot, error code(%d)\n", __FUNCTION__,
 retval);

I think it is right because at line 1564, the slot is turned off, and in
this line (1575) is checked the status to see if we got an error; if so,
the error number is shown.  This number is in 'retval', not in 'rc' ('rc'
does have the return of configure_new_device()).

drivers/pcmcia/tcic.c:63: warning: `version' defined but not used

From: Jens Axboe <axboe@suse.de>

AS does not correctly account requests inserted with INSERT_FRONT or
INSERT_BACK, barriers for example.  In other elevators, requeued requests also
go through the insert path, but AS has its own requeue handler which means the
code has never been tested.

Also, make inserting a barrier with INSERT_SORT imply INSERT_BACK, which is
the logical behaviour.  Previously such insertions weren't rigorously defined.
