Subject: Re: [PATCH v5 9/9] bio: Fix bio_flagged() so that it can be combined

I find the subject a little weird. What you're doing is to clean up
the C version, which also tends to micro-optimize the x86 assembly
generation for a specifi compiler. Which is good on two counts, so I'm
all for the patch, but I don't really think it's "combining", which
really made me think of testing two flags in one call.
