2731 6105 d 17 h jermar /trunk/uspace/srv/ Add the VFS_FREE operation. This operation frees up whatever resources used by
a file system node for which there is no name (i.e. an unlinked node).

Cleanup VFS operations enums and remove unneeded VFS operations.		  
2690 6145 d 9 h jermar /trunk/uspace/srv/ Make a distinction between VFS operations that are common to VFS and FS
implementations, operations that are VFS only and operations that are FS
implementations only.		  
2644 6168 d 14 h jermar /trunk/uspace/ Move incomplete fs interface from fat.h to libfs.  
2643 6168 d 15 h jermar /trunk/uspace/ VFS work.
Move FS registration code to libfs.		  
2639 6179 d 8 h jermar /trunk/uspace/srv/fs/fat/ FAT work.
Foundation for FAT dentry comparison function.
Beware of looking at the diff or risk loosing sanity.		  
2638 6180 d 11 h jermar /trunk/ Sync IPC comments with IPC code.  
2637 6180 d 11 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.		  
2635 6182 d 11 h cejka /trunk/ Function ipc_connect_me_to sends 3 user defined arguments now.
One argument added also to ipc_forward_fast.
Fixed devmap and improved its test.		  
2629 6189 d 9 h jermar /trunk/uspace/srv/fs/fat/ FAT work.
Add type describing FAT directory entry.		  
2628 6189 d 10 h jermar /trunk/uspace/srv/fs/fat/ FAT work.
Add type describing FAT boot sector.		  
2627 6189 d 11 h jermar /trunk/uspace/srv/fs/fat/ FAT work.
Start VFS_LOOKUP support in FAT.		  
2619 6194 d 9 h jermar /trunk/ 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().		  
2615 6195 d 19 h jermar /trunk/ Modify synchronous IPC to make use of all six syscall arguments. The preferred
means of synchronous communication is now via the set of ipc_call_sync_m_n()
macros, where m is the number of payload arguments passed to the kernel and n is
the number of return values. These macros will automatically decide between the
fast and the universal slow version of ipc_call_sync.		  
2588 6211 d 16 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.		  
2568 6243 d 0 h jermar /trunk/uspace/ Rename fibril_schedule_next_adv() to fibril_switch(). Rename
fibril_schedule_next() to fibril_yield(). Some fibril structures could be
uninitialized, set them to zero in fibril_setup(). For some fibrils, the stack
member can be NULL (e.g. every thread's first/main fibril); don't do free on
these stacks when cleaning up after a dead fibril.		  
2546 6247 d 20 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.		  
2543 6248 d 16 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.		  
2536 6253 d 11 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.		  
2534 6255 d 14 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 6256 d 10 h jermar /trunk/uspace/srv/fs/fat/ No need to call async_manager() at the end of fat.c's main().
