Subject: [PATCH v8 for-next 2/3] IB/core: Shifting initialization of device->cache_lock
Date: Mon, 12 Jul 2021 17:56:24 +0530	[thread overview]
Message-ID: <20210712122625.1147-3-anand.a.khoje@oracle.com> (raw)
In-Reply-To: <20210712122625.1147-1-anand.a.khoje@oracle.com>

The lock cache_lock of struct ib_device is initialized in function
ib_cache_setup_one(). This is much later than the device initialization
in _ib_alloc_device().

This change shifts initialization of cache_lock in _ib_alloc_device().
