VFS work.
Start implementing VFS side of VFS_OPEN.
Add vfs_node.c to contain VFS node related internal functions. |

VFS work.
Allocate the open filess array dynamically and protect access to it via a
per-connection futex. Defer its allocation until the client makes a first
VFS_OPEN request.
Actually call vfs_mount() and vfs_open(), respectively, when the VFS_MOUNT and
VFS_OPEN requests, respectively, are received from the client. |

Add ipc_answer_fast_[01] macros so that ipc_answer_fast() users don't have to
write zero arguments all the time. |

VFS work.
Introduce the notion of VFS_PAIR which corresponds to a file system instance,
and VFS_TRIPLET, which corresponds to a file system node. Separate vfs_triplet_t
and vfs_node_t as the former one is the stateless counterpart of the latter. |

Don't explicitly answer the IPC_M_DATA_SEND call in VFS_REGISTER.
It is done automatically in ipc_data_deliver(). |

Prevent race conditions when checking rootfs by taking a newly introduced
rootfs_futex. |

This is a checkpoint commit.
It introduces initial, still incomplete, code for VFS-side VFS_MOUNT request. |

VFS work.
Modify vfs_lookup_internal() to be able to work with an alternate root. This
will be useful for VFS_MOUNT support.
Improve observability and debuggability by explicitly zeroing out PLB after the
path has been looked up. |

VFS work.
Add fs_name_to_handle() function to abstract away the details of walking the
list of registered file systems, and in order to avoid code duplication. |

VFS work.
Upon FS registration via VFS_REGISTER, the client is assigned a unique file
system handle. When generating the VFS_LOOKUP request in VFS, we also need to
pass the device handle. Add function to transform file system handle to phone.
Implement basic multi-call VFS request serialization on VFS side. |

Modify the protocol so that VFS and FAT (or any other FS) have to share the Path
Lookup Buffer in read-only mode. |
|

Start support for the Patch Lookup Buffer.
Also add rootfs pointer. |

VFS work.
Describe the bottleneck of one VFS-FS connection in fat.c. Add a comment
outlining possible approaches.
Also in fat.c, the async_create_manager() _must_ be called as well as
async_set_client_connection(). The latter alows VFS to duplicate the connection.
Modify fat_connection() to ACK all IPC_M_CONNECT_ME_TO calls. |
