    Description

      libcfs_debug_dumplog() sets task state to INTERRUPTIBLE and then calls kthread_run() that might sleep.

      It's mostly harmless here, but still should be avoided as the kernel prints a nastygram about it when it happens.

      I guess just moving the state setting to after kthread_run call is all that's needed.
