The module parameters allow the timeouts to be extended, but only up to 255s, as the counters are bytes. [Fix] The underlying parameters are unsigned ints, so make the module parameters unsigned ints too, by picking patch http://lists.infradead.org/pipermail/linux-nvme/2017-September/012701.html (Trusty specific) This also requires picking the patch that converts the constant into a parameter, which is a clean cherry-pick. [Regression Potential] (X/Z/A) Very limited: only types of module parameters are changing, the patch is easily reviewable. (Trusty specific) Limited: a module parameter is added and its type is changed. The patches are easily reviewable. [Testing] (Trusty only) Boot tested on a c5.large instance on AWS which uses NVMe to boot. Verified that the system still boots with the patches, and that a timeout of 123456s is permitted.
