5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chao Yu <chao@xxxxxxxxxx>
[ Upstream commit fb9b65340c818875ea86464faf3c744bdce0055c ]
f2fs_move_file_range() doesn't support migrating compressed cluster
data, let's add the missing check condition and return -EOPNOTSUPP
for the case until we support it.
Fixes: 4c8ff7095bef ("f2fs: support data compression")
