CRYPTO_AUDITING_*_DATA defines a single USDT probe point for each invocation. This causes multiple context switches to happen if they are writen in series. This adds a new macro, CRYPTO_AUDITING_DATA and CRYPTO_AUDITING_DATAV, which take an array of events to limit the number of context switches. Signed-off-by: Daiki Ueno <[email protected]>
