From 40d36882c7dca295c631e3dc1e7b5a5382ee8a19 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Sun, 10 Dec 2023 19:35:44 +0800 Subject: [PATCH] f2fs: fix to check compress file in f2fs_move_file_range() [ 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.
