6.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> This reverts commit a78a8bcdc26de5ef3a0ee27c9c6c512e54a6051c which is commit a6ec83786ab9f13f25fb18166dee908845713a95 upstream. Something is currently broken in the f2fs code, Guenter has reported boot problems with it for a few releases now, so revert the most recent f2fs changes in the hope to get this back to a working filesystem.
