<title>shrink_dcache_sb speedup</title>

<content type='text'>
This patch makes shrink_dcache_sb consistent with dentry pruning policy.

On the first pass we iterate over dentry unused list and prepare some
dentries for removal.

However, since the existing code moves evicted dentries to the beginning of
the LRU it can happen that fresh dentries from other superblocks will be
inserted *before* our dentries.

This can result in significant slowdown of shrink_dcache_sb().  Moreover,
for virtual filesystems like unionfs which can call dput() during dentries
kill existing code results in O(n^2) complexity.

We observed 2 minutes shrink_dcache_sb() with only 35000 dentries.

To avoid this effects we propose to isolate sb dentries at the end
of LRU list.

<title>[NETNS]: Cleanup list walking in setup_net and cleanup_net</title>

I proposed introducing a list_for_each_entry_continue_reverse macro
to be used in setup_net() when unrolling the failed -&gt;init callback.

Here is the macro and some more cleanup in the setup_net() itself
to remove one variable from the stack :) The same thing is for the
cleanup_net() - the existing list_for_each_entry_reverse() is used.

Minor, but the code looks nicer.

There are many places in the kernel where the construction like

   foo = list_entry(head-&gt;next, struct foo_struct, list);

are used.
The code might look more descriptive and neat if using the macro

   list_first_entry(head, type, member) \
             list_entry((head)-&gt;next, type, member)

Here is the macro itself and the examples of its usage in the generic code.
 If it will turn out to be useful, I can prepare the set of patches to
inject in into arch-specific code, drivers, networking, etc.

  * make multi-line initial descriptions single line
  * denote some function names, constants and structs as such
  * change erroneous opening '/*' to '/**' in a few places

<title>[PATCH] add an RCU version of list splicing</title>

<content type='text'>
This patch is in support of the IPMI driver.  I have tested this with the
IPMI driver changes coming in the next patch.

Add a list_splice_init_rcu() function to splice an RCU-protected list into
another list.  This takes the sync function as an argument, so one would do
something like:

	INIT_LIST_HEAD(&amp;list);
	list_splice_init_rcu(&amp;source, &amp;dest, synchronize_rcu);

The idea being to keep the RCU API proliferation down to a dull roar.
