Subject: [PATCH 10/15] nvme: add Clang context annotations in fabric.c
Date: Wed, 10 Jun 2026 19:57:30 +0530	[thread overview]
Message-ID: <20260610142743.115898-11-nilay@linux.ibm.com> (raw)
In-Reply-To: <20260610142743.115898-1-nilay@linux.ibm.com>

The global nvmf_transports list is protected by nvmf_transports_rwsem
and the global nvmf_hosts list is protected by nvmf_hosts_mutex.

Annotate both lists with __guarded_by() so that Clang's context analysis
can validate accesses to the lists against the corresponding locking
requirements.
