perf: Use current->flags & PF_KTHREAD|PF_USER_WORKER instead of current->mm == NULL
[ Upstream commit 90942f9fac05702065ff82ed0bade0d08168d4ea ]
To determine if a task is a kernel thread or not, it is more reliable to
use (current->flags & (PF_KTHREAD|PF_USER_WORKERi)) than to rely on
current->mm being NULL. That is because some kernel tasks (io_uring
helpers) may have a mm field.
