Subject: [PATCH v2 07/17] md/raid5-ppl: Drop unused argument from ppl_handle_flush_request()
Date: Thu, 26 May 2022 10:35:54 -0600 [thread overview]
Message-ID: <20220526163604.32736-8-logang@deltatee.com> (raw)
In-Reply-To: <20220526163604.32736-1-logang@deltatee.com>
ppl_handle_flush_request() takes an struct r5log argument but doesn't
use it. It has no buisiness taking this argument as it is only used
by raid5-cache and has no way to derference it anyway. Remove
the argument.
No functional changes intended.
