John:
I have code fixing the BSD4.4-Lite code layering violations which
I'm in the process of making sure the patches are against -current.
This has some of the fixes necessary for SMP and multithreading,
as well as starting without a file system at all and dynamically
loading it all.
The idea is to eventually use pageable kernel code on startup and
throw it away later after the desirable replacement drivers have
loaded and probed correctly.
This will impact file systems that aren't in the -current snapshot
I have, since the cn_pnbuf buffer is no longer expected to be
deallocated by the underlying file system (the caller that did
the allocating is expected to do the cleanup).
I'll pack up the patches and ship them to Freefall either tonight
or tomorrow night.
Contact me at terry@lambert.org if this is a problem!
