Which most # definitely isn't what we want either. # # The obvious fix was always just to do the alignment last, but I had # moved it earlier just to make the patch smaller and the code look # simpler. Duh. It certainly made _me_ look simple. # # Fixes: 1c24a186398f ("fs: fd tables have to be multiples of BITS_PER_LONG") # Reported-and-tested-by: Jason A.
