Turbo linux 7 sems to be agreeing with Curtis,
bi: ブロックデバイスに送られたブロック (blocks/s)。
bo: ブロックデバイスから受け取ったブロック (blocks/s)。
Sorry it's in Japanese but bi says "blocks sent to block device" and bo is
"blocks received from block device".
I don't know that much about it but the actual output seems to suggest that
the man page is wrong. I find it just the slightest bit amusing that such
errors in the docs should be translated faithfully when translating
invariably introduces errors of it's own ;)
Regards
Iain
