Stop the JFS filesystem from using iget() and read_inode(). Replace
jfs_read_inode() with jfs_iget(), and call that instead of iget(). jfs_iget()
then uses iget_locked() directly and returns a proper error code instead of an
inode in the event of an error.
jfs_fill_super() returns any error incurred when getting the root inode
instead of EINVAL.

Implement nobh in new aops. This is a bit tricky. FWIW, nobh_truncate is
now implemented in a way that does not create blocks in sparse regions,
which is a silly thing for it to have been doing (isn't it?)
ext2 survives fsx and fsstress. jfs is converted as well... ext3
should be easy to do (but not done yet).

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.

This patch changes mpage_readpages() and get_block() to get the disk mapping
information for multiple blocks at the same time.
b_size represents the amount of disk mapping that needs to mapped. On the
successful get_block() b_size indicates the amount of disk mapping thats
actually mapped. Only the filesystems who care to use this information and
provide multiple disk blocks at a time can choose to do so.
No changes are needed for the filesystems who wants to ignore this.

the implementation is straight forward, except
for the fact that the attributes have to be mapped
to match with the ext2 ones to avoid a separate
tool for manipulating them (this could be avoided
when using a separate flag field in the on-disk
representation, but the overhead is minimal)
a special jfs_ioctl is added to allow for the new
JFS_IOC_GETFLAGS and JFS_IOC_SETFLAGS calls.
a helper function jfs_set_inode_flags() to transfer
the flags from the on-disk version to the inode
minor changes to allow flag inheritance on inode
creation, as well as a cleanup of the on-disk
flags (including the new ones)
beforementioned helper to map between ext2 and jfs
versions of the new flags ...
the JFS_SECRM_FL and JFS_UNRM_FL are not done yet
and I'm not 100% sure they are worth the effort,
the rest seems to work out of the box ...

Clash due to new delete_inode behavior (the filesystem now needs to do
the truncate_inode_pages() call itself).
Signed-off-by: Linus Torvalds <torvalds@osdl.org>
Update the file systems in fs/ implementing a delete_inode() callback to
call truncate_inode_pages(). One implementation note: In developing this
patch I put the calls to truncate_inode_pages() at the very top of those
filesystems delete_inode() callbacks in order to retain the previous
behavior. I'm guessing that some of those could probably be optimized.

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!
