Subject: [PATCH v1 1/8] lib/uuid: Introduce uuid_{be|le}_cmp_p{p}() helpers
Date: Fri, 21 Apr 2017 17:46:38 +0300 [thread overview]
Message-ID: <20170421144645.45189-1-andriy.shevchenko@linux.intel.com> (raw)
New helpers take pointers to uuid_{be|le} as parameters.
When using them on a raw data we don't need to do an ugly dereference
and, in some cases, a type casting.
