Will Andrews 58567a1b4e ZFS: Fix a panic while unmounting a busy filesystem. ... This particular scenario was easily reproduced using a NFS export. When the first 'zfs unmount' occurred, it returned EBUSY via this path, while vflush() had flushed references on the filesystem's root vnode, which in turn caused its v_interlock to be destroyed. The next time 'zfs unmount' was called, vflush() tried to obtain this lock, which caused this panic. Since vflush() on FreeBSD is a definitive call, there is no need to check vfsp->vfs_count after it completes. Simply #ifdef sun this check.
