daa35edc0a [PATCH] uml: remove empty hostfs_truncate method
Calling truncate() on hostfs spits a kernel warning "Something isn't
implemented here", but it still works fine.

Indeed, hostfs i_op->truncate doesn't do anything.  But hostfs_setattr() ->
set_attr() correctly detects ATTR_SIZE and calls truncate() on the host.  So
we should be safe (using ftruncate() may be better, in case the file is
unlinked on the host, but we aren't sure to have the file open for writing,
and reopening it would cause the same races; plus nobody should expect UML to
be so careful).

So, the warning is wrong, because the current implementation is working.  Al,
am I correct, and can the warning be therefore dropped?

fef266580e [PATCH] update filesystems for new delete_inode behavior
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.

a0d43df931 [PATCH] uml: hostfs: unuse ROOT_DEV
Minimal patch removing uses of ROOT_DEV; next patch unexports it.  I've
opposed this, but I've planned to reintroduce the functionality without using
ROOT_DEV.

a2e4b972c9 [PATCH] uml: remove 2_5compat.h
Remove old useless header that was used in Ye Olde Times during 2.4->2.5
porting to abstract differences.  It's definitions are no more used anyway, so
let's finally kill it.

ffa0aea681 [PATCH] uml - hostfs: avoid buffers
Use this:
	.set_page_dirty = __set_page_dirty_nobuffers,

We already dropped the inclusion of <linux/buffer_head.h>, and we don't have a
backing block device for this FS.

"Without having looked at it, I'm sure that hostfs does not use buffer_heads.
So setting your ->set_page_dirty a_op to point at __set_page_dirty_nobuffers()
is a reasonable thing to do - it'll provide a slight speedup."

This speedup is one less spinlock held and one less conditional branch, which
isn't bad.

1da177e4c3 Linux-2.6.12-rc2
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!
