Simplify the IPC_M_DATA_WRITE protocol. Do not pass the source address space
virtual address to the recipient. This feature was not used anyway. Now
IPC_M_DATA_WRITE and IPC_M_DATA_READ are feature-aligned. |

Rename IPC_M_DATA_SEND to IPC_M_DATA_WRITE. Now, when we also add
IPC_M_DATA_READ, it will not clash and cause confusion with userspace wrappers
such as ipc_data_receive(). Rename the forementioned wrappers to
ipc_data_write_send(), ipc_data_write_receive() and ipc_data_write_deliver(). |

VFS work.
During VFS_REGISTER, use strncmp() instead of strcmp().
Add one excessive convenience byte to vfs_info.name to support the
above-mentioned change. In case the fs name spans all available
characters, make sure this convenience byte is zero. |

Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5. |

Modify ipc_answer_*() to make use of all six syscall arguments. The recommended
means of answering calls is via the ipc_answer_m() macros (where m denotes the
number of return arguments) that automatically decide between the fast register
version or the slow universal version of ipc_answer(). |

VFS work.
vfs_grab_phone() must disable fibril preemption in order to avoid deadlock with
other fibrils of the same thread that might be trying to vfs_grab_phone() too. |

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

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

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

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. |

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. |

VFS work.
The VFS_REGISTER is now fully implemented by both vfs and fat servers. Thanks to
the debugging dprintf()'s, I was able to fix little errors here and there to
make them actually work.
Modified vfs and fat service makefiles so that the two are not built as drivers
and can therefore print to standard output. Added many debugging dprintf()'s.
Change the amd64 boot configuration to load vfs and fat. |

VFS work.
Implement VFS_REGISTER part of the protocol in the FAT file system.
IPC work.
Rename ipc_data_send_accept() to ipc_data_receive() and ipc_data_send_answer()
to ipc_data_deliver(). Introduce ipc_data_send(). |

VFS work.
Added mandatory VFS_LOOKUP
Handling of VFS_REGISTER request should be now more or less complete.
Added code that inserts the new fs_info structure into the list of registered
filesystems and creates a callback connection to the client FS. |
