Hi Liu Qiang,

The patch is fine except for the title and comment.  It's too vague to
say I/O load balancing.  You need explicit description like "add
interrupt coalescing support" as title.

How about:

Adds support for interrupt coalescing feature to reduce interrupt
events.  Provides mechanism of adjusting coalescing count and timeout
tick by sysfs on runtime, so that tradeoff of latency and CPU load can
be made depending on applications.
