[CRIU] [PATCH 0/3] BTRFS engine, v2

[Cyrill Gorcunov]

The main change from previous version is that instead of matching paths
we lookup for subvolume device id and use its root (mount point) id which
should match the one obtained from DIAG module.

IOW the key function is

dev_t btrfs_try_demangle(dev_t dev)
{
	struct btrfs_subvol_node *node;

	node = btrfs_node_lookup_dev(dev);
	if (node)
		dev = (dev_t)node->subvol_root->m->s_dev;

	return dev;
}

Cyrill Gorcunov (3):
  mount: Introduce BTRFS engine
  proc_parse: Find subvolumes on BTRFS mount points
  sk-unix: Don't fail if socket path lays on btrfs volume
