This was a single patch until v3. Some preliminary cleanups were

introduced for submounts in this v4.


This can be tested with a custom virtiofsd implementing FUSE_SYNCFS, here:


https://gitlab.com/gkurz/qemu/-/tree/fuse-sync


v4: - submount fixes

    - set nodeid of the superblock in the request (Miklos)


v3: - just keep a 64-bit padding field in the arg struct (Vivek)


v2: - clarify compatibility with older servers in changelog (Vivek)

    - ignore the wait == 0 case (Miklos)

    - 64-bit aligned argument structure (Vivek, Miklos)


Greg Kurz (5):

  fuse: Fix leak in fuse_dentry_automount() error path

  fuse: Call vfs_get_tree() for submounts

  fuse: Make fuse_fill_super_submount() static

  virtiofs: Skip submounts in sget_fc()

  virtiofs: propagate sync() to file server
