Version-Release number of selected component (if applicable):


How reproducible:

Consistently

Steps to Reproduce:
1. Create a tier volume and FUSE mount it.
2. Create a large file FILE1 so it will take some time to migrate. This is created on the hot tier by default
3. After FILE1 is demoted, append some data to it to trigger file promotion
4. While FILE1 is being promoted, create a hardlink hlink to FILE1 in some other directory


Actual results:
Once FILE1 has been migrated, hlink no longer exists

Expected results:
Once FILE1 has been migrated, hlink should still exist
