# HP/HPE Smart Array controllers can't handle IO:s much larger than 1 MiB with
# good performance although they can handle 4 MiB without error. The driver
# advertise the stripe size as maximum IO size which can be substantially
# larger for bulk IO setups.
#
# Install this as
# /etc/udev/rules.d/90-smartarray-limitiosize.rules
# to limit max_sectors_kb to 512, the default before Linux 3.18.22.
