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>.

Thanks,
Miklos
