Modified files:
sys/geom/bde g_bde_work.c
Log:
Fix a problem and slightly improve the ENOMEM handling:
Give up the entire bio as soon as we detect a problem.
When we detect a problem, give up the bio by contributing the
remainder with ENOMEM, rather than kicking the bio back right
away.
If we failed on a non-first iteration we previously could end up
modifying fields in the bio after we delivered it. This could
account for memory corruption (none directly reported) on machines
with GBDE.
