New sentence, new line.

Remove the paragraph saying interfaces will change without warning.
Note that a stable version of puffs first appeared in NetBSD 5.0.

branches: 1.12.4; 1.12.6;
Punctuation markup nit.

branches: 1.11.4; 1.11.6;
Implement lazy contexts for file systems using puffs_mainloop().
Previously each request was executed on its own callcontext and
switched to every time the request was being processed. Now requests
borrow the mainloop context and switch only if/when they yield.
This takes two context switches away from a file system request
bringing down the typical amounts 2->0 (e.g. dtfs) and 4->2 (e.g.
psshfs).

The interfaces for manually executing requests changed a bit:
puffs_dispatch_create() and puffs_dispatch_exec() must now be used.
They are not tested, as nothing in-tree wants them and I doubt
anyone else is really interested in them either.

Also do some misc code cleanup related to execution contexts. The
"work-in-progress checkpoint" committed over a year ago was starting
to look slightly weed-infested.

update to match reality

puffs_cc_getusermount(), puffs_cc_getspecific() and puffs_docc() are dead.

Fix a typo that has migrated across files.

Add puffs_cc_schedule() which marks a pcc runnable and will pass
execution to it when in the main loop the next time.

branches: 1.6.4;
Xr puffs_framebuf

improve descriptions and markup

add puffs_cc_getspecific(pcc), which is shorthand for:
puffs_getspecific(puffs_cc_getusermount(pcc))

document puffs_docc

Sort SEE ALSO.

Bring the documentation slightly more into sync with the current
reality. It's still really a far cry from proper documentation,
though.
