Subject: [PATCH 02/36] scsi: scsi_debug: Prepare for enabling lock context analysis
Date: Thu, 12 Mar 2026 14:15:13 -0700 [thread overview]
Message-ID: <20260312211636.3245119-3-bvanassche@acm.org> (raw)
In-Reply-To: <20260312211636.3245119-1-bvanassche@acm.org>
Annotate the functions that perform conditional locking with
__no_context_analysis to prevent that the Clang thread-safety analyzer
complains about these functions.
