crash.subsystem.storage.blocksq.for_each_request_in_queue(queue: gdb.Value) → Iterable[gdb.Value]

Iterates over each struct request in request_queue

This method iterates over the request_queue’s queuelist and returns a request for each member.

Parameters:queue – The struct request_queue used to iterate. The value must be of type struct request_queue. Yields:gdb.Value – Each struct request contained within the request_queue’s queuelist. The value is of type struct request.

crash.subsystem.storage.blocksq.request_age_ms(request: gdb.Value) → int

Returns the age of the request in milliseconds

This method returns the difference between the current time (jiffies) and the request’s start_time, in milliseconds.

Parameters:request – The struct request used to determine age. The value is of type struct request. Returns:

Difference between the request’s start_time and

current jiffies in milliseconds.

Return type:int
