Subject: Re: SCSI sr driver: parallel writes to optical serialized which hurts
 performance (sr_mutex)

Hi Wakko,

If I remember correctly I did see you commenting on discussions on
either the Otto Meta patch, or another that proposed to remove the
mutex entirely. I was unaware of any others.

Do you have more information on why this never resulted in a succesful
concerted effort to get a patch in the kernel tree? Do the patches
have drawbacks or have they never been submitted properly? If the
latter, we might endeavor it?

Best,
Johan
