Subject: [PATCH v8 04/13] nvmet: make nvmet_copy_ns_identifier() non-static
Date: Wed, 28 Aug 2019 15:54:20 -0600	[thread overview]
Message-ID: <20190828215429.4572-5-logang@deltatee.com> (raw)
In-Reply-To: <20190828215429.4572-1-logang@deltatee.com>

This function will be needed by the upcoming passthru code.

Passthru will need an emulated version of identify_desclist which
copies the eui64, uuid and nguid from the passed-thru controller into
the request SGL.

[chaitanya.kulkarni@wdc.com: this was factored out of a patch
 originally authored by Chaitanya]
