Modified files:
sys/geom geom_io.c
Log:
When sending request once again because of ENOMEM, reset bio_children
and bio_inbed fields to 0. Without this change we can end up with
I/O leakage in some rare situations.
I tested this change by putting failure probability mechanism simlar
to this used in NOP class into g_clone_bio(9) function, so it was
able to return NULL with the given probability.
