-# DESCRIPTION:
-# See ZoL issues #5866 and #8858.  This test will ensure the fixes for
-# these specific issues have no regression.
-#
-# Exercise the functions zfs_suspend_fs / zfs_resume_fs / zfs_rezget.
-# The test will ensure that we reach zfs code that compares file
-# generation numbers and fetches extended attributes.
-#
-# STRATEGY:
-# 1. Import a pool that has txg number > 2^32.
-# 2. Take snapshot and do send with an online receive.
-# 3. EIO is expected when accessing the received file-system.
-# 4. Access extended attribute. (previously this would panic)
-# 5. Take second snapshot, write some data.
-# 6. Rollback.
-# 7. Access the resulting file-system. (previously every accesss would give EIO)
