19# DESCRIPTION:
20# Verify 'zfs recv' can forcibly unmount filesystem while receiving
21# stream.
22#
23# STRATEGY:
24# 1. Create snapshot of file system
25# 2. Make a zfs filesystem mountpoint busy
26# 3. Receive filesystem with force flag.
27# 4. Verify that stream was received or failed on Linux.
