Subject: [PATCH 09/30] staging: lustre: discard LOWEST_BIT_SET()
Date: Mon, 21 May 2018 14:35:12 +1000 [thread overview]
Message-ID: <152687731269.24196.12873538902260418047.stgit@noble> (raw)
In-Reply-To: <152687724799.24196.7718555295926047576.stgit@noble>
This macro is only used once to test if a value is
a power of two. So use is_power_of_2() instead and
discard the macro.
