* Name: can_readahead_signal
|
|
*
|
|
* Description:
|
|
* Read-ahead data has been buffered. Signal all threads waiting for
|
|
* read-ahead data to become available.
|
|
*
|
|
* When read-ahead data becomes available, *all* of the workers waiting
|
|
* for read-ahead data will be executed. If there are multiple workers
|
|
* waiting for read-ahead data then only the first to execute will get the
|
|
* data. Others will need to call can_readahead_notifier_setup() once
|
|
* again.
|
|
*
|
|
* Input Parameters:
|
|
* conn - The CAN connection where read-ahead data was just buffered.
|
|
*
|
|
* Returned Value:
|
|
* None.
