This patch add an anonymous inode source, to be used for files that need
and inode only in order to create a file*. We do not care of having an
inode for each file, and we do not even care of having different names in
the associated dentries (dentry names will be same for classes of file*).
This patch cuts out lots of code from epoll, by reusing the anonymous
inode source of patch 2/3.

hi,
Is there a way how to make kernel thread more faster?
I put some of my code to the kthread, but I noticed that kthread sends data
more slow
than original driver without kthread.
Please post a link to your driver source code.

[PATCH] SLUB The unqueued slab allocator v4
V3-V4
- Rename /proc/slabinfo to /proc/slubinfo. We have a different format after
all.
- More bug fixes and stabilization of diagnostic functions. This seems
to be finally something that works wherever we test it.
- Serialize kmem_cache_create and
Unlimited kmalloc size and removal of general caches =4.
We can directly use the page allocator for all allocations 4K and larger. This
means that no general slabs are necessary and the size of the allocation passed
to kmalloc() can be arbitrarily large. Remove the useless general caches over
Guarantee a mininum number of objects per slab
The number of objects per slab is important for SLUB because it determines
the number of allocations that can be performed without having to consult
per node slab lists. Add another boot option min_objects=xx that
allows the configuration of the
