[for-6.1 v2 0/2] virtiofsd: Add support for FUSE_SYNCFS request

[Greg Kurz]

FUSE_SYNCFS allows the client to flush the host page cache.
This isn't available in upstream linux yet, but the following
tree can be used to test:

v2: - based on new version of FUSE_SYNCFS
      https://listman.redhat.com/archives/virtio-fs/2021-April/msg00166.html
    - propagate syncfs() errors to client (Vivek)

  Update linux headers to 5.12-rc8 + FUSE_SYNCFS
