Taking the write lock prior to entering that function is a problem because this function is full of conditions that most of the time can lead to eliminating the lock. This commit first moves the write lock inside the function and passes the extra argument required to implement stktable_touch_remote() and stktable_touch_local(). It also renames the function to remove the underscores since there's no other variant and it's exported under this name (probably an old rename that was not propagated). The code was stressed under 48 threads using 3 trackers on the same table. It already shows a tiny 3% improvement from 187k to 193k rps.
