[PATCH 0/4] list: introduce list_next/prev_entry

[Oleg Nesterov <oleg@redhat.com>]

Hello.

Not sure who maintains list.h, hopefully this is -mm material.

It is really annoying that we do not have list_next/prev_entry,
they can have a lot of users, including list.h itself.

And in fact list_next_entry() is already defined in events/core.c
and bnx2x_sp.c, this proves that it is really handy. That is why
1/4 comes as a separate patch because it touches the code outside
of list.h.

3/4 is minor, but I think makes sense anyway.

4/4 is just the random example of usage outside of list.h,
list_entry(child->d_u.d_child.next, struct dentry, d_u.d_child)
is hardly readable.

None of this patches changes the compiled code.

Oleg.
