Bug description:
  This is a request to add the following upstream commit to both Ubuntu
  16.04.1 and 16.04.2:

  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/scsi/ses.c?id=9373eba6cfae48911b977d14323032cd5d161aae

  Without this patch, the symlink in sysfs which binds a SAS device to
  an enclosure slot does not get created. This makes disk hotplug near
  impossible on large JBOD disk drawers.

  You should be able to do:

  ls /sys/block/sdb/device/ | grep enclosure

  and see something like:

  enclosure_device:1

  If you cd to this directory, you can then access the SES controls for
  that slot to flash the LED to assist in locating the disk to replace a
  failed disk.

  Currently with 16.04.1 and 16.04.2, these symlinks are not getting
  created.
