Merge tag 'fuse-update-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse

Pull fuse updates from Miklos Szeredi:
 "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>"
