In Commit 7d74f492e4dd0034a61458eb80f70b1d2862ed07,author said:
"This allows drivers who call this function to be compiled modularly.
Otherwise, a driver who is interested in this type of functionality
has to implement their own get_task_comm() call, causing code
duplication in the Linux source tree."
But author did not say about set_task_comm().At present,I used it but
compiled error.To the same purpose, it should export.
