sys/kern kern_subr.c
Log:
MFC (part of 1.34: set p->p_priority in uio_yield() _after_ entering
the "criticial region". This merge is mainly for completeness. Wrong
settings of p->p_priority just modify the indeterminacy of scheduling,
and this setting is not as wrong as some others -- I believe it is
harmless in the current implementation of the scheduler. The bug just
turned up in a search for settings of p_priority that don't maintain
certain invariants.
