Subject: [PATCH v1] lightnvm: pblk: Replace guid_copy() with export_guid()/import_guid()
Date: Wed, 22 Apr 2020 16:06:11 +0300 [thread overview]
Message-ID: <20200422130611.45698-1-andriy.shevchenko@linux.intel.com> (raw)
There is a specific API to treat raw data as GUID, i.e. export_guid()
and import_guid(). Use them instead of guid_copy() with explicit casting.
