New revision: 269353
URL: http://svnweb.freebsd.org/changeset/base/269353
Log:
Fix breakage introduced by r256843: removing the SA_CCB_WAITING bit
left some of the decisions based on its counterpart, SA_CCB_BUFFER_IO
being random. As a result, propagation of the residual information
for the SPACE command was broken, so the number of filemarks
encountered during a SPACE operation was miscalculated. Consequently,
systems relying on properly tracked filemark counters (like Bacula)
fell apart.
The change also removes a switch/case in sadone() which r256843
degraded to a single remaining case label.
