Oh, and since I didn't react initially, let me react now that Andrei found a bug here: why was this patch auto-selected for 5.5 stable in the first place?
It wasn't really a fix, and there's no Fixes: tag or stable tag in there. Yeah, there's a reference to an old commit, but that one isn't even a kernel commit.
Yeah, the performance improvements are quite nice if you hit the case this matters for, but still..
