sys/sys bio.h
Log:
Oops, broke the build there. Uninline biodone() now that it is non-trivial.
Introduce biowait() function. Currently there is a race condition and the
mitigation is a timeout/retry. It is not obvious what kind of locking (if any)
is suitable for BIO_DONE, since the majority of users take are of this
themselves, and only a few places actually rely on the wakeup.
