[for-6.1 v3 0/3] 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:

https://gitlab.com/gkurz/linux/-/tree/virtio-fs-sync

v3: - track submounts and do per-submount syncfs() (Vivek)
    - based on new version of FUSE_SYNCFS (still not upstream)
      https://listman.redhat.com/archives/virtio-fs/2021-May/msg00025.html

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)
