static simplelock initializer (and simplelock too). The fastpath
is still lockless, so doesn't make a difference in terms of
performance.
Also fixes a hanging bug if the once routine returned an error.
It does not retry after an error occurs, as I can't really imagine
fruitful semantics for that.
- Change minimal time-quantum to ~20 ms.
- Thus remove unneeded pool in M2, and unused sched_lwp_exit().
- Do not increase l_slptime twice for SCHED_4BSD (regression fix).
UDF. Future users could be msdosfs, ufs, nilfs2 (when ready), cd9660 etc.
Note that its not the same as UFS's DIRHASH support; UFS would need a good
cleanup/splitout of directory operations to adopt to this new directory
hashing support since most directory operations are interweaved with the
vnops itself. This is a TODO.
Let's look for threads in the TARGET process, not in the
debugger process (gdb). Noticed when a KASSERT fired while
running gdb on a threaded app.
I will adjust wrstuden-revivesa-base-3 to include this change.
free a buffer. This will fail if the buffer owner has a chance to
modify the BC_DONTFREE flag before putphysbuf() examines it.
Fix by removing get/putphysbuf() and BC_DONTFREE. Physio_done() now
has an explicit test for a buffer coming from the call of physio().

Thanks to Stathis Kamperis for finding the issues and testing the fixes.

"case" statement and was forwarded to the slave side, returning the
data which can be read by the slave.
The new behaviour also matches Linux and OSF/1.
in pmf_deregister, don't constantly realloc. just shift everything closer
