6dac02a5e1 [JFFS2] Fix slab panic
When JFFS22 is unable to read the root inode, the bad root inode object is not
freed and remains sticked in the jffs2_i slab cache. When we further try to
free the slab cache (e.g., on rmmod jffs2), slab allocator subsystem panics.

2b79adcca1 [JFFS2] Use f->target instead of f->dents for symlink target
JFFS2 uses f->dents to store the pointer to the symlink target string (in case
the inode is symlink). This is somewhat ugly to use the same field for
different reasons. Introduce distinct field f->target for this purpose.
Note, f->fragtree, f->dents, f->target may probably be put in a union.

4e57b68178 [PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.

5e1efe4931 [PATCH] jffs/jffs2: remove wrong function prototypes
This patch removes prototypes for the generic_file_open and
generic_file_llseek functions.

Besides being superfluous because they are already present in fs.h, they
were also wrong because the actual functions aren't weak functions.

2fb1e3086d [PATCH] jffs2: fix symlink error handling
The current calling conventions for ->follow_link() are already fairly
complex.

What we have is
	1) you can return -error; then you must release nameidata yourself
	   and ->put_link() will _not_ be called.
	2) you can do nd_set_link(nd, ERR_PTR(-error)) and return 0
	3) you can do nd_set_link(nd, path) and return 0
	4) you can return 0 (after having moved nameidata yourself)

jffs2 follow_link() is broken - it has an exit where it returns
-EIO and leaks nameidata.
