Jan Kucera found an missing call to mutex_unlock() with his static code
checker. It's an unlikely error path to hit in the real world, but it
should be fixed.

The comment above the function says one of its return value is -EIO,
and also the caller of diAlloc() checks for -EIO:
struct inode *ialloc(struct inode *parent, umode_t mode)
{
...
rc = diAlloc(parent, S_ISDIR(mode), inode);
if (rc) {
jfs_warn("ialloc: diAlloc returned %d!", rc);
if (rc == -EIO)
make_bad_inode(inode);
...

This mirrors Jan Kara's patches for ext3. This patch makes sure that
changes made to inode->i_flags are reflected on disk for jfs. It also
moves a call of jfs_set_inode_flags() to be more consistent with where
jfs_get_inode_flags() is called.

Run this:
#!/bin/sh
for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
echo "De-casting $f..."
perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
done
And then go through and reinstate those cases where code is casting pointers
to non-pointers.
And then drop a few hunks which conflicted with outstanding work.

This eliminates the i_blksize field from struct inode. Filesystems that want
to provide a per-inode st_blksize can do so by providing their own getattr
routine instead of using the generic_fillattr() function.
Note that some filesystems were providing pretty much random (and incorrect)
values for i_blksize.

OS/2 doesn't initialize the uid, gid, or unix-style permission bits. The
uid, gid, & umask mount options perform pretty much like those for the fat
file system, overriding what is stored on disk. This is useful for users
sharing the file system with OS/2.
I implemented a little feature so that if you mask the execute bit, it
will be re-enabled on directories when the appropriate read bit is unmasked.
I didn't want to implement an fmask & dmask option.

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.

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.

JFS was creating a new IAG (inode aggregate group) in one address
space, and afterwards, accessing it from another. This could lead to
complications when cache pages contain more than one page of jfs
metadata. This patch causes the IAG to be initialized in the same
address space that it is subsequently accessed with.
This also elimitates an I/O, but IAG's aren't created too often.

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!
