Hi Linus,

Here's a collection of fscache and cachefiles fixes and misc small
cleanups.  The two main fixes are:

 (1) Add a missing unmark of the inode in-use mark in an error path.

 (2) Fix a KASAN slab-out-of-bounds error when setting the xattr on a
     cachefiles volume due to the wrong length being given to memcpy().

In addition, there's the removal of an unused parameter, removal of an
unused Kconfig option, conditionalising a bit of procfs-related stuff and
some doc fixes.
