1 v 1.10: August 19, 2003
2
3 First UCLA release -- no longer publically maintained or released
4 by Sensoria. This version is the UCLA (public) fork.
5
6 Kernel module now, finally, has correct fine-grained locking that
7 does not assume atomicity of kernel code. In other words, FUSD is
8 now safe for SMP machines, preemptible kernels, etc.
9
10 Python bindings have been contributed by Brian Warner.
11
12 The old /dev/fusd control file has been moved into a subdirectory,
13 /dev/fusd/control.
14
15 Human-readable status is now available in /dev/fusd/status.
16
17 By doing an ioctl() on /dev/fusd/status, it can also give you
18 binary status information -- reads will return an array of
19 fusd_status_t structures.
20
21 Many, many subtle bugs have been fixed (e.g. rare race
22 conditions).
23
24 Lots of updates and bug-fixes to the documentation, which was
25 carefully read by a number of people who were actually trying to
26 use it.

29 v 1.04: February 5, 2002
30
31 Change from the point of view of clients: Selecting on an FD being
32 provided by a FUSD driver will return as part of the exception set
33 if the driver disappears. Useful for client programs that want to
34 gracefully handle driver crashes.
35
36 Some changes to get semantics of poll_diff (closer to) correct -
37 will require some more changes later
38
39 Reduced max number of messages dispatched per call to
40 fusd_dispatch. very slightly less efficient, but more fair.
41
42 Protocol change - max name length now 47 instead of 31
43
44 Minor kernel module fixes: Fixed the malloc.h/slab.h confusion,
45 and added MODULE_LICENSE.
46
47 Minor API change: fusd_register now takes a const char *
48 name instead of a char *name.
