If we are touching this code, the return value here should be error

hmm, It should stop at 3. I will take a look.
Even if it stops at 3, that's still wrong because it's failed to
process the entire user input....
xfs_db> write u3.bmx.startblock x3rgfdw
u3.bmx.startblock = 0
i.e. it accepts garbage rather than erroring out.
as does all the other writes ...

Fixing convert_arg() is beyond the scope of just this patch.
Sure, but I'm not asking you to fix all of convert_args in this
patch, just asking you to do a complete job of fixing the bitval
input processing in this patch.
But, seeing as you've raised that convert_args() has other broken
paths, can you also write new patches to address those issues? It
won't take you long while all this code is fresh in your mind, and
if you do it now it won't get dropped on the floor until somebody
else hits it a couple of years down the track...
It needs to be split up. write_string() needs string inputs,
write_struct() need numeric inputs. Who uses the UUID-style hex blocks?
It feels like a black hole of time.
It goes on my 'off the clock' to do list.
