From e76f201f69e76653f3e7301f2183421d9267e2f5 Mon Sep 17 00:00:00 2001 From: zhenwei pi Date: Fri, 28 Jul 2023 10:20:03 +0800 Subject: throttle: use enum ThrottleDirection instead of bool is_write enum ThrottleDirection is already there, use ThrottleDirection instead of 'bool is_write' for throttle API, also modify related codes from block, fsdev, cryptodev and tests.
