2550 6256 d 3 h cejka /trunk/ Fixed naming convention in IPC.  
2549 6256 d 5 h jermar /trunk/uspace/srv/vfs/ 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.		  
2548 6256 d 6 h jermar /trunk/uspace/srv/vfs/ 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.		  
2547 6256 d 6 h cejka /trunk/ Added basic support for device mapper.  
2546 6256 d 9 h jermar /trunk/uspace/srv/ 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.		  
2544 6257 d 1 h jermar /trunk/uspace/srv/vfs/ VFS work.
Proto implementation of VFS-side vfs_lookup_internal().		  
2543 6257 d 4 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 6257 d 7 h jermar /trunk/uspace/srv/vfs/ VFS work.
Start support for the Patch Lookup Buffer.
Also add rootfs pointer.		  
2541 6257 d 7 h jermar /trunk/uspace/ Header cleanup.
Move off_t, size_t and ssize_t into sys/types.h.
Get rid off the non-standard and dummy types.h.		  
2540 6257 d 22 h jermar /trunk/uspace/srv/vfs/ VFS work.
Introduce basic types representing a file system node and an open file.		  
2539 6258 d 4 h jermar /trunk/uspace/srv/console/ Cstyle and other minor fixes in the console code.  
2536 6262 d 0 h jermar /trunk/uspace/srv/ 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.		  
2535 6264 d 3 h jermar /trunk/uspace/srv/vfs/ Move VFS_REGISTER functionality into a separate file.  
2534 6264 d 3 h jermar /trunk/uspace/ In async_new_connection(), be more robust in the case that the function
is called by the server directly after its client accepts the
IPC_M_CONNECT_TO_ME call.

In fat.c main(), kill the "main" fibril and switch to the connection
fibril.		  
2533 6264 d 23 h jermar /trunk/uspace/srv/fs/fat/ No need to call async_manager() at the end of fat.c's main().  
2532 6265 d 1 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 6266 d 0 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().		  
2530 6266 d 15 h jermar /trunk/uspace/lib/libc/generic/ Pseudo thread -> fibril change in several comments.  
2529 6267 d 2 h jermar /trunk/uspace/ Turn the empty fs service into the beginning of FAT support.
Start implementing the VFS protocol for fat.c.		  
2528 6267 d 2 h jermar /trunk/uspace/lib/libc/ Modify parts of the build system and libc to support building applications on
paths with differing distances from lib/libc (e.g. uspace/srv/ns and
uspace/srv/fs/fat).
