Subject: net: remove get_task_comm() and print task comm directly
X-Git-Tag: microblaze-v6.16~79^2~54
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=b619c7ac21853558d08a40a31132950bfecc9383;p=linux-2.6-microblaze.git

net: remove get_task_comm() and print task comm directly

Since task->comm is guaranteed to be NUL-terminated, we can print it
directly without the need to copy it into a separate buffer.  This
simplifies the code and avoids unnecessary operations.
