Analyze and fix the following issue in the Linux kernel code: mac80211: fix sign error in pid controller
Problem Details: While testing the pid rate controller in mac80211_hwsim, I noticed that once the controller reached 54 Mbit rates, it would fail to lower the rate when necessary. The debug log shows: 1945 186786 pf_sample 50 3534 3577 50 My interpretation is that the fixed point scaling of the target error value (p...

Problem Details: We can race with the unmount of an fs and the stopping of a kthread where we will free the block group before we're done using it.
