There're many truncated kthreads in the kernel, which may make trouble
for the user, for example, the user can't get detailed device
information from the task comm.

This patchset tries to improve this problem fundamentally by extending
the task comm size from 16 to 24, which is a very simple way. 

It can't be that simple if we're on v7 and at 11 patches!

It would be helpful if you included links to earlier postings.  I can
only find v5 and v6 in my inbox, so I fear I'm going to re-ask some
questions which were already answered.

Why can't we shorten the names of these kthreads?  You didn't
give any examples, so I can't suggest any possibilities.
