Robert Watson d2c205d5de A few locking fixes and cleanups to pfil hook registration, ... unregistration, and execution: - Add some brackets for clarity and trim a bit of vertical whitespace. - Remove comments that may not contribute to clarity, such as "Lock" before acquiring a lock and "Get memory" before allocating memory. - During hook registration, don't drop pfil_list_lock between checking for a duplicate and registering the hook, as this leaves a race condition by failing to enforce the "no duplicate hooks" invariant. - Don't lock the hook during registration, since it's not yet in use. - Document assumption that hooks will be quiesced before being unregistered. - Don't write-lock hooks during removal because they are assumed quiesced. - Rename "done" label to "locked_error" to be clear that it's an error path on the way out of hook execution.
