2596 6221 d 6 h jermar /trunk/uspace/srv/vfs/ VFS work.
Implement VFS node hash table management.
 
2593 6223 d 3 h jermar /trunk/uspace/srv/vfs/ A lot of more VFS prototyping.
VFS_OPEN gets reasonably complete, fix a limitation that prevented file
structures from being shared by multiple file descriptors, add functions for
file descriptor management, introduce unlink_futex and two new VFS operations
VFS_UNLINK and VFS_RENAME.
 
2589 6224 d 8 h jermar /trunk/uspace/srv/vfs/ 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.
 
2588 6224 d 8 h jermar /trunk/uspace/ Add ipc_answer_fast_[01] macros so that ipc_answer_fast() users don't have to
write zero arguments all the time.
 
2569 6254 d 10 h jermar /trunk/uspace/ Tiny refinement of if-else_if-else statement in vfs_register.c.  
2560 6259 d 5 h jermar /trunk/uspace/srv/vfs/ VFS work.
Start VFS_OPEN.
 
2552 6260 d 3 h jermar /trunk/uspace/srv/vfs/ VFS work.
This is a checkpoint commit.
It introduces initial, still incomplete, code for VFS-side VFS_MOUNT request.
 
2543 6261 d 8 h jermar /trunk/uspace/srv/ VFS work.
Modify the protocol so that VFS and FAT (or any other FS) have to share the Path
Lookup Buffer in read-only mode.
 
2542 6261 d 11 h jermar /trunk/uspace/srv/vfs/ VFS work.
Start support for the Patch Lookup Buffer.
Also add rootfs pointer.
 
2535 6268 d 6 h jermar /trunk/uspace/srv/vfs/ Move VFS_REGISTER functionality into a separate file.  
2532 6269 d 4 h jermar /trunk/ 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.
 
2531 6270 d 3 h jermar /trunk/uspace/ 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().
 
2527 6272 d 12 h jermar /trunk/ 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.
 
2526 6273 d 8 h jermar /trunk/uspace/ VFS work.
Delve deeper into VFS_REGISTER.
 
2523 6273 d 14 h jermar /trunk/ VFS work.

Now, each VFS connection fibril will accept requests in a loop. The idea is that
each connection will be potentially reused for multiple requests before it is
closed by the server.

More VFS_REGISTER bits. Make use of the IPC_M_DATA_SEND wrappers introduced in
the previous commit.

Add enum members for more VFS operations.
 
2521 6275 d 3 h jermar /trunk/uspace/srv/vfs/ VFS work.
Start implementing the VFS_REGISTER request.
 
2520 6275 d 4 h jermar /trunk/uspace/ VFS work.
Turn the dummy skeleton into a dummy skeleton that can handle connections.
There are already traces of the VFS protocol.
 
2518 6276 d 3 h jermar /trunk/uspace/ One occurrence of the left-over term 'pseudo thread' replaced with 'fibril' in
the rd task.

Start the vfs task. Now it is dummy, but integrated into the sources.
