New events have been added in kernel 4.14 ("bind" and "unbind").
Systemd maintainer suggests to modify "add|change" branches.
This patches implements their suggestions. There is no issue yet because
new event types are not used in md.
Please see systemd announcement for details[1].

Instead of /usr/bin/sh, and /usr/bin/echo, use /bin/sh and shell
built-in echo respectively. This makes
udev-md-raid-safe-timeouts.rules to be compatible with both usr-merged
and split-usr systems alike.

These udev rules attempt to set a safe kernel controller
timeout for disks containing RAID level 1 or higher
partitions for commodity disks which do not have SCTERC
capability, or do have it but it is disabled.
No attempt is made to change the STCERC settings on devices
which support it.
This attempts to mitigate the problem described here:
https://raid.wiki.kernel.org/index.php/Timeout_Mismatchhttp://strugglers.net/~andy/blog/2015/11/09/linux-software-raid-and-drive-timeouts/
where the kernel controller may timeout on a read from a
disk after the default timeout of 30 seconds and consequently
cause mdraid to regard the disk as dead and eject it from the
RAID array.
The mitigation is to set the timeout to 180 seconds for disks
which contain a RAID level 1 or higher partition.
