Subject: [PATCH 1/6] csky: remove BS check for FAULT_FLAG_ALLOW_RETRY
Date: Thu, 11 Sep 2025 02:52:23 +0100 [thread overview]
Message-ID: <20250911015223.GA2604499@ZenIV> (raw)
In-Reply-To: <20250911015124.GV31600@ZenIV>
flags are initialized as FAULT_FLAG_DEFAULT, and the only thing done
to that afterwards is |=; since FAULT_FLAG_DEFAULT already includes
FAULT_FLAG_ALLOW_RETRY, it's guaranteed to remain there all along.
