There are several mount options that don't show up in /proc/mounts. Add
them in and clean up the showargs code at the same time.

Sparse trips over the locking order in xlog_recover_do_efd_trans() when
xfs_trans_delete_ail() drops the ail lock. Because the unlock is
conditional, we need to either annotate with a "fake unlock" or change the
structure of the code so sparse thinks the function always unlocks.
Reordering the code makes it simpler, so do that.

These are mostly locking annotations, marking things static, casts where
needed and declaring stuff in header files.

We need xfs_bulkstat() to report inode stat for inodes with link count
zero but reference count non zero.
The fix here:
http://oss.sgi.com/archives/xfs/2007-09/msg00266.html
changed this behavior and made xfs_bulkstat() to filter all unlinked
inodes including those that are not destroyed yet but held by reference.
The attached patch returns back to the original behavior by marking the
on-disk inode buffer "dirty" when di_mode is cleared (at that time both
inode link and reference counter are zero).

XFS_IOC_GETVERSION, XFS_IOC_GETXFLAGS and XFS_IOC_SETXFLAGS all take a
"long" which changes size between 32 and 64 bit platforms.
So, the ioctl cmds that come in from a 32-bit app aren't as expected, for
example on GETXFLAGS,
unknown cmd fd(3) cmd(80046601){t:'f';sz:4}
due to the size mismatch.
So, use instead the 32-bit version of the commands for compat ioctls, and
other than that it doesn't take any more manipulation.
Also, for both native and compat versions, just define them to the values
as defined in fs.h

This macro is unused an all other acros in this family operate on native
types, so we most likely won't grow a user either.

There is no need to lock any page in xfs_buf.c because we operate on our
own address_space and all locking is covered by the buffer semaphore. If
we ever switch back to main blockdeive address_space as suggested e.g. for
fsblock with a similar scheme the locking will have to be totally revised
anyway because the current scheme is neither correct nor coherent with
itself.

Refactoring xfs_mountfs() to call sub-functions for logical chunks can
help save a bit of stack, and can make it easier to read this long
function.
The mount path is one of the longest common callchains, easily getting to
within a few bytes of the end of a 4k stack when over lvm, quotas are
enabled, and quotacheck must be done.
With this change on top of the other stack-related changes I've sent, I
can get xfs to survive a normal xfsqa run on 4k stacks over lvm.

Mostly trivial conversion with one exceptions: h_num_logops was kept in
native endian previously and only converted to big endian in xlog_sync,
but we always keep it big endian now. With todays cpus fast byteswap
instructions that's not an issue but the new variant keeps the code clean
and maintainable.

- the various assign lsn macros are replaced by a single inline,
xlog_assign_lsn, which is equivalent to ASSIGN_ANY_LSN_HOST except
for a more sane calling convention. ASSIGN_LSN_DISK is replaced
by xlog_assign_lsn and a manual bytespap, and ASSIGN_LSN by the same,
except we pass the cycle and block arguments explicitly instead of a
log paramter. The latter two variants only had 2, respectively one
user anyway.
- the GET_CYCLE is replaced by a xlog_get_cycle inline with exactly the
same calling conventions.
- GET_CLIENT_ID is replaced by xlog_get_client_id which leaves away
the unused arch argument. Instead of conditional defintions
depending on host endianess we now do an unconditional swap and shift
then, which generates equal code.
- the unused XLOG_SET macro is removed.

xfs_ioctl.c passes around vnode pointers quite a lot, but all places
already have the Linux inode which is identical to the vnode these days.
Clean the code up to always use the Linux inode.

We were already filling the Linux struct statfs anyway, and doing this
trivial task directly in xfs_fs_statfs makes the code quite a bit cleaner.
While I was at it I also moved copying attributes that don't change over
the lifetime of the filesystem outside the superblock lock.
xfs_fs_fill_super used to get the magic number and blocksize through
xfs_statvfs, but assigning them directly is a lot cleaner and will save
some stack space during mount.

xfs_iocore_t is a structure embedded in xfs_inode. Except for one field it
just duplicates fields already in xfs_inode, and there is nothing this
abstraction buys us on XFS/Linux. This patch removes it and shrinks source
and binary size of xfs aswell as shrinking the size of xfs_inode by 60/44
bytes in debug/non-debug builds.

Currently there is an indirection called ioops in the XFS data I/O path.
Various functions are called by functions pointers, but there is no
coherence in what this is for, and of course for XFS itself it's entirely
unused. This patch removes it instead and significantly reduces source and
binary size of XFS while making maintaince easier.

No need to allocate a bhv_vattr_t on stack and call xfs_getattr to update
a few fields in the Linux inode from the XFS inode, just do it directly.
And yes, this function is in dire need of a better name and prototype,
I'll do in a separate patch, though.

There is no reason to go through xfs_iomap for the BMAPI_UNWRITTEN because
it has nothing in common with the other cases. Instead check for the
shutdown filesystem in xfs_end_bio_unwritten and perform a direct call to
xfs_iomap_write_unwritten (which should be renamed to something more
sensible one day)

There is no reason to go into the iomap machinery just to get the right
block device for an inode. Instead look at the realtime flag in the inode
and grab the right device from the mount structure.
I created a new helper, xfs_find_bdev_for_inode instead of opencoding it
because I plan to use it in other places in the future.

Simplify vnode tracing calls by embedding function name & return addr in

Also do a lot of vnode->inode renaming for consistency, while we're at it.

A large part of xfs_sync_inodes is conditional on the SYNC_BDFLUSH which
is never passed to it. This patch removes it and adds an assert that
triggers in case some new code tries to pass SYNC_BDFLUSH to it.

Trond and Bruce,
This is a patch for 2.6.25. This is the same version that was sent out
on December 12 for review (no comments to date).
To simplify the RPC/RDMA client and server build configuration, make
SUNRPC_XPRT_RDMA a hidden config option that continues to depend on
SUNRPC and INFINIBAND. The value of SUNRPC_XPRT_RDMA will be:
- N if either SUNRPC or INFINIBAND are N
- M if both SUNRPC and INFINIBAND are on (M or Y) and at least one is M
- Y if both SUNRPC and INFINIBAND are Y
In 2.6.25, all of the RPC/RDMA related files are grouped in
net/sunrpc/xprtrdma and the net/sunrpc/xprtrdma/Makefile builds both
the client and server RPC/RDMA support using this config option.

If the inode is flagged as having an invalid mapping, then we can't rely on
the PageUptodate() flag. Ensure that we don't use the "anti-fragmentation"
write optimisation in nfs_updatepage(), since that will cause NFS to write
out areas of the page that are no longer guaranteed to be up to date.
A potential corruption could occur in the following scenario:
client 1 client 2
=============== ===============
fd=open("f",O_CREAT|O_WRONLY,0644);
write(fd,"fubar\n",6); // cache last page
close(fd);
fd=open("f",O_WRONLY|O_APPEND);
write(fd,"foo\n",4);
close(fd);
fd=open("f",O_WRONLY|O_APPEND);
write(fd,"bar\n",4);
close(fd);
-----
The bug may lead to the file "f" reading 'fubar\n\0\0\0\nbar\n' because
client 2 does not update the cached page after re-opening the file for
write. Instead it keeps it marked as PageUptodate() until someone calls
invaldate_inode_pages2() (typically by calling read()).

Convert jfs_ioctl over to not use the BKL. The only potential race
I could see was with two ioctls in parallel changing the flags
and losing the updates. Use the i_mutex to protect against this.

ocfs2: Negotiate locking protocol versions.

Currently, when ocfs2 nodes connect via TCP, they advertise their
compatibility level. If the versions do not match, two nodes cannot speak
to each other and they disconnect. As a result, this provides no forward or
backwards compatibility.
This patch implements a simple protocol negotiation at the dlm level by
introducing a major/minor version number scheme for entities that
communicate. Specifically, o2dlm has a major/minor version for interaction
with o2dlm on other nodes, and ocfs2 itself has a major/minor version for
interacting with the filesystem on other nodes.
This will allow rolling upgrades of ocfs2 clusters when changes to the
locking or network protocols can be done in a backwards compatible manner.
In those cases, only the minor number is changed and the negotatied protocol
minor is returned from dlm join. In the far less likely event that a
required protocol change makes backwards compatibility impossible, we simply
bump the major number.

It's possible that the caller of sysfs_remove_group messed up and passed in an attribute group that was not really registered to this kobject. But don't panic for such a foolish error, spit out a warning about what happened, and continue on our way safely.

The "whole_disk" attribute was not properly converted in the block
device conversion earlier, and if the file is read, bad things can
happen. This patch fixes this, making the attribute an empty one,
preserving the original functionality.
Many thanks to David Miller for finding this, and pointing me in the
proper place within the block code to look.

posix_acl_clone does a memory allocation and sets a reference count, so
