Re: HEADS UP - major structure size changes in HEAD
I pushed another rev to the lwkt_token code which makes the
structure larger and thus effects many major structures in the
kernel.
People tracking master should do another full kernel + modules build.
I am going to start tying in the new global tokens this week. I may
be able to do the whole thing but if not the rules for tying in the
tokens are pretty easy... every global procedure that needs a
particular token simply acquires it unconditionally for the duration
of the procedure. I have optimized the code paths dealing with
recursive tokens to reduce overhead significantly so extra recursive
acquisitions and releases do not cost us much in terms of efficiency.
I'll solicit additional help once I've determined that my methodology
is sound. I think I can get the VM path completely locked up this
weekend. These are still global tokens but we will at least be making
progress.
