Hello Martin, During the 2018 edition of LSF/MM there was a session about increasing SCSI disk probing concurrency. This patch series implements what has been proposed during that session, namely: - Make sure that the driver core is aware of asynchronous SCSI LUN probing. - Avoid unnecessary serialization between sd_probe() and sd_remove() because this could lead to a deadlock.
Please consider this patch series for kernel v4.20. Thanks, Bart.
