If cow_file_range_inline() failed, when called from compress_file_range(), we were tagging the locked page for writeback, end its writeback and unlock it, but not marking it with an error nor setting AS_EIO in inode's mapping flags. This made it impossible for a caller of filemap_fdatawrite_range (writepages) or filemap_fdatawait_range() to know that an error happened. And the return value of compress_file_range() is useless because it's returned to a workqueue task and not to the task calling filemap_fdatawrite_range (writepages). This change applies on top of the previous patchset starting at the patch titled: "[1/5] Btrfs: set page and mapping error on compressed write failure" Which changed extent_clear_unlock_delalloc() to use SetPageError and mapping_set_error().
