Subject: [PATCH 07/13] module: mark module_mutex static
Date: Tue, 2 Feb 2021 13:13:28 +0100 [thread overview]
Message-ID: <20210202121334.1361503-8-hch@lst.de> (raw)
In-Reply-To: <20210202121334.1361503-1-hch@lst.de>
Except for two lockdep asserts module_mutex is only used in module.c.
Remove the two asserts given that the functions they are in are not
exported and just called from the module code, and mark module_mutex
static.
