At some point changes to clk_set_rate and clk_set_parent introduced a
bug whereby NULL struct clk pointers were treated as an error. This is
in violation of the API in include/linux/clk.h. Reintroduce graceful
handling of NULL clk's by bailing from clk_set_rate and clk_set_parent
with return codes

Just realised that we have dropped linux-iio (could have sworn it was
there back at the beginning of this thread) from the cc list so put
it back. Might be worth adding lmsensors as well. Will leave that up
to Guenter.

We checked pfmemalloc by slab unit, not page unit. You can see this
in is_slab_pfmemalloc(). So other pages don't need to be set/cleared

And, therefore we should check pfmemalloc in page flag of first page,

Now, there are a few field in struct slab, so we can overload these
over struct page. This will save some memory and reduce cache footprint.
After this change, slabp_cache and slab_size no longer related to
a struct slab, so rename them as freelist_cache and freelist_size.
These changes are just

When programming ioapic pinX more than once, current code
does not check whether the later attr (trigger&polarity) is the
same as the former or not. This causes a broken semantic.
Fix it by reporting -EBUSY, when attr is different.

It is more understandable that kmem_getpages() return struct page.
And, with this, we can reduce one translation from virt addr to page and
makes better code than before. Below is a change of this patch.

Now, bufctl is not proper name to this array.
So change it.

With build-time size checking, we can overload the RCU head over the LRU
of struct page to free pages of a slab in rcu context. This really help to
implement to overload the struct slab over the struct page and this
eventually reduce memory usage and cache footprint of the SLAB.

If we use 'struct page' of first page as 'struct slab', there is no
advantage not to use __GFP_COMP. So use __GFP_COMP flag for all the cases.

Hi.
I noticed that tcpdump shows many dropped packets on new kernels.
It looks like that:
# tcpdump -n -i eth0 -c 10
...
10 packets captured
10 packets received by filter
0 packets dropped by kernel
4294967268 packets dropped by interface
