[PATCH v6 0/1] virtiofsd: Add support for FUSE_SYNCFS request |

FUSE_SYNCFS allows the client to flush the host page cache.
v6: - drop ! announce_submounts part for now, only the root inode is
synced in this case
v5: - split announce_submounts and ! announce_submounts to separate patches
for easier review (but could be squashed together)
- track submounts directly in lo_inode structure following the same
logic as FUSE_ATTR_SUBMOUNT (i.e. directory with either st_dev or
stx_mnt_id different from parent)
v4: - based on upstream linux FUSE_SYNCFS
- added support for the '-o announce_submounts' case, i.e. client sends
a FUSE_SYNCFS request for each submount (identified by its root inode)
- adapted the case without '-o announce_submounts' so that syncfs() is
no longer called with lo->mutex held
v3: - track submounts and do per-submount syncfs() (Vivek)
- based on new version of FUSE_SYNCFS (still not upstream)

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)
