You know what.. we should make checkpatch report an error for memory barriers that don't have a comment.
I know this isn't added by this patch, but every time I see something like it I cry a little.
Actually if it was a new line, it would have been reported, at least in theory:
# check for memory barriers without a comment. if ($line =~ /\b(mb|rmb|wmb|read_barrier_depends|smp_mb|smp_rmb|smp_wmb|smp_read_barrier_depends)(/) { if (!ctx_has_comment($first_line, $linenr)) { CHK("MEMORY_BARRIER", "memory barrier without comment\n" . $herecurr); } }
