Hi, I would like to highlight the need to review and comment the direction of commit 8a9de22b049f332a574eead7fa738678397f47fc in the korg git tree. http://git.kernel.org/?p=linux/storage/multipath-tools/.git;a=commit;h=8a9de22b049f332a574eead7fa738678397f47fc This work addresses a long-standing short-coming of the path checking subsystem, inducing unreliable behaviour in face of over-burdened storage hardware and long hangs in CLI and multipath.8 interactions. I posted on linux-scsi ml to try and gather information on SG/AIO programming, but still no luck. If someone there happen to know the subject, please feed data.
