3Document some possible user-visible changes that may take place.
4For a complete list, please dump my brain and excavate.
5
6  * figure out what do to with struct vattr, maybe introduce some
7    vattr-like puffs-specific structure (translation costs?) instead
8    of direct exposure
9
10  * make puffs_node opaque outside the library
11
12  * make it possible to cache symlink names and getattr results in
13    the kernel ... although I'm not as critically concerned with the
14    kernel caching as I am with userlevel caching
15
16  * try to implement a kernel policy for VOP_ACCESS, it's called
17    very very often - but this requires some kernel caching
18
19    + also try to figure out how to implement it in cases where it's
20      more difficult to do, e.g. how can we know readdir on sshfs will
21      fail without actually trying to read the directory?  If we fail
22      readdir itself, it's treated as success
23
24  * implement file system layering .. this will most likely bring
25    massive changes to how the ops vector is handled, for instance.
26    pcc/pu division should stay quite like the way it is now, but
27    maybe there will be layer specific ops.
28
29  * make puffs more like kernel vfs - or make kernel vfs more like puffs
30
31  * decide what to do about setback operations.  they kind of violate
32    the transparency of FAF for op handling
33
34  * remove flags parameter to puffs_init and replace with something
35    more generic
36
37  * fix incoming requests to not require memcpy with continuations
38    (not user-visible?)
39
40  * make continuations play with libpthread, lib/36011 (not user-visible?)
41
42  * clean up the request dispatching / continuation code (not user-visible?)
