Subject: [PATCH v3 2/5] pstore/blk: Move verify_size() macro out of function
Date: Wed, 16 Jun 2021 09:40:40 -0700	[thread overview]
Message-ID: <20210616164043.1221861-3-keescook@chromium.org> (raw)
In-Reply-To: <20210616164043.1221861-1-keescook@chromium.org>

There's no good reason for the verify_size macro to live inside the
function. Move it up with the check_size() macro and fix indenting.
