Pull fuse fixes from Miklos Szeredi:
 "This fixes a leaked inode lock in an error cleanup path and a data
  consistency issue with copy_file_range().

  It also adds a new flag for the WRITE request that allows userspace
  filesystems to clear suid/sgid bits on the file if necessary"

* tag 'fuse-fixes-5.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse:
  fuse: extract helper for range writeback
  fuse: fix copy_file_range() in the writeback case
  fuse: add FUSE_WRITE_KILL_PRIV
  fuse: fallocate: fix return with locked inode
