This patch add EXPORT_SYMBOL(filemap_write_and_wait) and use it.

See mm/filemap.c:

And changes the filemap_write_and_wait() and filemap_write_and_wait_range().

Current filemap_write_and_wait() doesn't wait if filemap_fdatawrite()
returns error.  However, even if filemap_fdatawrite() returned an
error, it may have submitted the partially data pages to the device.
(e.g. in the case of -ENOSPC)

<quotation>
Andrew Morton writes,

If filemap_fdatawrite() returns an error, this might be due to some
I/O problem: dead disk, unplugged cable, etc.  Given the generally
crappy quality of the kernel's handling of such exceptions, there's a
good chance that the filemap_fdatawait() will get stuck in D state
forever.
</quotation>

So, this patch doesn't wait if filemap_fdatawrite() returns the -EIO.

Trond, could you please review the nfs part?  Especially I'm not sure,
nfs must use the "filemap_fdatawrite(inode->i_mapping) == 0", or not.

This patch fixes up a few problems with jfs's reserved inodes.

1. There is no need for the jfs code setting the I_DIRTY bits in i_state.
   I am ashamed that the code ever did this, and surprised it hasn't been
   noticed until now.

2. Make sure special inodes are on an inode hash list.  If the inodes are
   unhashed, __mark_inode_dirty will fail to put the inode on the
   superblock's dirty list, and the data will not be flushed under memory
   pressure.

3. Force writing journal data to disk when metapage_writepage is unable to
   write a metadata page due to pending journal I/O.

The fix in inode.c is a real bug.  It could result in undeleted, yet
unconnected files on big-endian hardware.

The others are trivial.

I'm finally getting around to cleaning out debug code that I've never used.
There has always been code ifdef'ed out by _JFS_DEBUG_DMAP, _JFS_DEBUG_IMAP,
_JFS_DEBUG_DTREE, and _JFS_DEBUG_XTREE, which I have personally never used,
and I doubt that anyone has since the design stage back in OS/2.  There is
also a function, xtGather, that has never been used, and I don't know why it
was ever there.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
