History
kib ade28bdd40 The buffers b_vflags field is not always properly protected by 
bufobj lock. If b_bufobj is not NULL, then bufobj lock should be
held when manipulating the flags. Not doing this sometimes leaves
BV_BKGRDINPROG to be erronously set, causing softdep' getdirtybuf() to
stuck indefinitely in "getbuf" sleep, waiting for background write to
finish which is not actually performed.

Add BO_LOCK() in the cases where it was missed.
