This change should qualify for an SRU. However, Canonical does not have the described hardware. We will need help from Huawei to test the SRU. Can Huawei commit to the following steps?
1) Test a PPA build with this fix (both 4.15 and 4.18) by 2019-03-27. Canonical can prepare this PPA. 2) After official Ubuntu kernel build, re-test both kernels to verify the fix.

Code change is all within an "if" statement that meets these restrictions. A bug in this code could possibly reduce the speed of an otherwise working disk connection.
