Hi Linus,

Please pull from:

git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git tags/fuse-update-4.20

As well as the usual bug fixes, this adds the following new features:

- cached readdir and readlink
- max I/O size increased from 128k to 1M
- improved performance and scalability of request queues
- copy_file_range support

The only non-fuse bits are trivial cleanups of macros in <linux/bitops.h>.
