>Description:
Race condition in zfs module when running vdev_geom_open():
It first opens geom by path in read/write/exclusive mode and checks device guid comparing to cache, if guid mismatches it closes geom (generating g_dev_taste event as it was last write client on geom) and searches all system devices looking for cached guid, if that still fails it tries to open geom by path in read/write/exclusive and fails because g_dev_taste kicked in just before with read/exclusive mode.
Found this problem both on 8.0-RELEASE and 9.0-CURRENT.
Full log for bored ones:
