Subject: [PATCH 6/6] tapdisk-ioemu: Fix shutdown condition
|
|
|
|
Even when opening the only image a tapdisk-ioemu instance is
|
|
responsible for fails, it can't immediately shut down. blktapctrl
|
|
still wants to communicate with tapdisk-ioemu and close the disk.
|
|
|
|
This patch changes tapdisk-ioemu to count the connections to
|
|
blktapctrl rather than the number of opened disk images.
|
|
