22# Description:
23# Verify FREEOBJECTS record frees sequential objects (See
24# https://github.com/zfsonlinux/zfs/issues/6694)
25#
26# Strategy:
27# 1. Create three files with sequential object numbers, f1 f2 and f3
28# 2. Delete f2
29# 3. Take snapshot A
30# 4. Delete f3
31# 5. Take snapshot B
32# 6. Receive a full send of A
33# 7. Receive an incremental send of B
34# 8. Fail test if f3 exists on received snapshot B
