[PATCH v2 0/5] Fix crash due to NBD export leak

[Vladimir Sementsov-Ogievskiy]

Hi all!

We've faced crash bug, which is reproducing on master branch as well.
The case is described in 03, where fix is suggested.
New iotest in 05 crashes without that fix.

v2:
01: reword commit msg, add Eric's r-b
02: fix type in commit msg, add Eric's r-b
03: rewrite
v1:04 split into 04 (iotests.py improvement) and 05(new test)


Vladimir Sementsov-Ogievskiy (5):
  iotests: QemuIoInteractive: use qemu_io_args_no_fmt
  iotests.py: QemuIoInteractive: print output on failure
  nbd: make nbd_export_close_all() synchronous
  iotests.py: filter_testfiles(): filter SOCK_DIR too
  iotests: test shutdown when bitmap is exported through NBD
