So we have to convert to new API for all filesystems, which is done in
one patch. Some filesystems are easy to convert (just replace
kmem_cache_alloc() to alloc_inode_sb()), while other filesystems need to
do more work.

From what I can tell, three are 54 file systems for which it was a
trivial one-line change, and two (f2fs and nfs42) that were a tad bit
more complex.

In order to make it easy for maintainers of different
filesystems to review their own maintained part, I split the patch into
patches which are per-filesystem in this version. I am not sure if this
is a good idea, because there is going to be more commits.

What I'd actually suggest is that you combine all of the trivial file
system changes into a single commit, and keep the two more complex
changes for f2fs and nfs42 in separate commits.
