Hello,
I've got a big box of audio CDs to read, so I hooked up a load of SATA
CDROM drives to a machine (Intel motherboard AHCI, and SATA SiI3124
controllers - in this example one was attached to each host controller),
so that I could read them in parallel.
I'm using kernel 3.16.3, with cdparanoi

I'm trying out some local changes which removes the ex-BKL mutex from
sr_block_ioctl() in sr.c, and instead uses a per-drive mutex which I've
added to cdrom_device_in

I've tested the IDE and SCSI subsystem patches, but I don't have any

. paride has received a few commits this year (and is listed as being
maintained)
. The change is trivial
. It fixes a performance regression wh
