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.

2683 6147 d 14 h jermar /trunk/uspace/srv/vfs/ Introduce the open file lock. Modify vfs_rdwr() to take this lock into account
when reading or writing from/to an open file.

2682 6147 d 17 h jermar /trunk/uspace/ Fix type in declaration of VFS node rwlock.
Introduce a dedicated type for futexes. Make the existing futex code use this
newly introduced type and fix formatting in futex.c.

2680 6147 d 18 h jermar /trunk/uspace/ Add basic rwlock API for uspace so that VFS can be designed/implemented using
this API. So far, the implementation of this API merely wraps futexes into
rwlocks. Real rwlocks are wanted by ticket #54.

Using the new rwlock API, replace the VFS node content futex with an rwlock.
Lock the contents rwlock as reader on reads and as writer on writes.

2679 6151 d 10 h jermar /trunk/uspace/srv/vfs/ Rename unlink_futex to namespace_futex and introduce a new futex for serializing
concurrent access to a VFS node's contents by multiple clients.

2678 6153 d 13 h jermar /trunk/uspace/ The IPC_M_SHARE_* and IPC_M_DATA_* calls pass through 3 stages. Rename the send,
receive and deliver wrappers to names ending with 'start', 'receive' and
'finalize', respectively. This should make it clearer for dummies.

2677 6153 d 14 h jermar /trunk/ Rename IPC_M_AS_AREA_SEND to IPC_M_SHARE_OUT. Rename IPC_M_AS_AREA_RECV to
IPC_M_SHARE_IN. Provide user-friendly wrappers for these methods so that even
dummies can get it right. Some applications using simpler protocols still use
these methods directly.

2676 6153 d 20 h jermar /trunk/ 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.

2660 6161 d 11 h jermar /trunk/ 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().
