reflink: change block sharing with constant refcount
Ensure that we can handle the case where the refcount stays the same even though the actual sharers changes. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Eryu Guan <eguan@redhat.com>

# FS QA Test No. 358
|

#
|
||||
# Share an extent amongst a bunch of files such that the refcount
|
||||
# stays the same while the rate of change of the set of owners is
|
||||
# steadily increasing. For example, an extent of 32 blocks is owned
|
||||
# by 32 files. At block 1, change one of the owners. At block 2,
|
||||
# change 2 of the owners, and so on.
