4 | Subject: [PATCH] fastboot: hold the BKL over the async init call sequence | ||
5 | |||
6 | Regular init calls are called with the BKL held; make sure | ||
7 | the async init calls are also called with the BKL held. | ||
8 | While this reduces parallelism a little, it does provide | ||
9 | lock-for-lock compatibility. The hit to prallelism isn't too | ||
10 | bad, most of the init calls are done immediately or actually | ||
11 | block for their delays. | ||
