This adds the fiemap inode_operation, which for us converts the
fiemap values & flags into a getbmapx structure which can be sent
to xfs_getbmap. The formatter then copies the bmv array back into
the user's fiemap buffer via the fiemap helpers.
If we wanted to be more clever, we could also return mapping data
for in-inode attributes, but I'm not terribly motivated to do that
just yet.

Preliminary work to hook up fiemap, this allows us to pass in an
arbitrary formatter to copy extent data back to userspace.
The formatter takes info for 1 extent, a pointer to the user "thing*"
and a pointer to a "filled" variable to indicate whether a userspace
buffer did get filled in (for fiemap, hole "extents" are skipped).
I'm just using the getbmapx struct as a "common denominator" because
as far as I can see, it holds all info that any formatters will care
about.
("*thing" because fiemap doesn't pass the user pointer around, but rather
has a pointer to a fiemap info structure, and helpers associated with it)

XFS gets the sign of the error wrong in several places when
gathering the error from generic linux functions. These functions
return negative error values, while the core XFS code returns
positive error values. Hence when XFS inverts the error to be
returned to the VFS, it can incorrectly invert a negative
error and this error will be ignored by the syscall return.
Fix all the problems related to calling filemap_* functions.

Now that we've stopped using the Linux inode cache when can trivally
support the inode64 mount option on 32bit architectures. As far as the
kernel and most userspace is concerned this works perfectly, but
applications still using really old stat and readdir interfaces will get
an EOVERFLOW error when hitting an inode number not fitting into 32
bits (that problem of course also exists when using these applications
on a 64bit kernel).
Note that because inode64 is simply a mount option we can currently
mount a filesystem having > 32 bit inode numbers and cause a variety of
problems, all this is solved but this patch which enables XFS_BIG_INUMS,
even when inode64 is not used.

Currently there's no ->open method set for directories on XFS. That
means we don't perform any check for opening too large directories
without O_LARGEFILE, we don't check for shut down filesystems, and we
don't actually do the readahead for the first block in the directory.
Instead of just setting the directories open routine to xfs_file_open
we merge the shutdown check directly into xfs_file_open and create
a new xfs_dir_open that first calls xfs_file_open and then performs
the readahead for block 0.

If we are syncing data in xfs_sync_inodes_ag(), the VFS inode must still
be referencable as the dirty data state is carried on the VFS inode. hence
if we can't get a reference via igrab(), the inode must be in reclaim
which implies that it has no dirty data attached.
Leave such inodes to the reclaim code to flush the dirty inode state to
disk and so avoid attempting to access the VFS inode when it may not exist
in xfs_sync_inodes_ag().
Version 4:
o don't reference linux inode until after igrab() succeeds
Version 3:
o converted unlock/rele to an xfs_iput() call.
Version 2:
o change igrab logic to be more linear
o remove initial reclaimable inode check now that we are using
igrab() failure to find reclaimable inodes
o assert that igrab failure occurs only on reclaimable inodes
o clean up inode locking - only grab the iolock if we are doing
a SYNC_DELWRI call and we have a dirty inode.

If the last block of the AG has inodes in it and the AG is an exactly
power-of-2 size then the last inode in the AG points to the last block in
the AG. If we try to find the next inode in the AG by adding one to the
inode number, we increment the inode number past the size of the AG. The
result is that the macro XFS_INO_TO_AGINO() will strip the AG portion of
the inode number and return an inode number of zero.
That is, instead of terminating the lookup loop because we hit the inode
number went outside the valid range for the AG, the search index returns
to zero and we start traversing the radix tree from the start again. This
results in an endless loop in xfs_sync_inodes_ag().
Fix it be detecting if the new search index decreases as a result of
incrementing the current inode number. That indicate an overflow and hence
that we have finished processing the AG so we can terminate the loop.

With the combined linux and XFS inode, we need to ensure that the combined
structure is not freed before the generic code is finished with the inode.
As it turns out, there is a case where the XFS inode is freed before the
linux inode - when xfs_reclaim() is called from ->clear_inode() on a clean
inode, the xfs inode is freed during that call. The generic code
references the inode after the ->clear_inode() call, so this is a use
after free situation.
Fix the problem by moving the xfs_reclaim() call to ->destroy_inode()
instead of in ->clear_inode(). This ensures the combined inode structure
is not freed until after the generic code has finished with it.
