Some of them could easily exceed that,\nand Jiaming Zhang found a few places where that can happen with syzbot.\n\nThe descriptions are debugging aids and aren't required to be unique, so\nlet's just pass in static strings and eliminate this path to failure.\nNote this patch touches a number of commits, most of which were merged\nbetween 6.6 and 6.14."
