Subject: [PATCH 5/7] drbd: don't set max_write_zeroes_sectors in decide_on_discard_support
Date: Wed, 6 Mar 2024 15:03:30 +0100 [thread overview]
Message-ID: <20240306140332.623759-6-philipp.reisner@linbit.com> (raw)
In-Reply-To: <20240305134041.137006-1-hch@lst.de>
From: Christoph Hellwig <hch@lst.de>
fixup_write_zeroes always overrides the max_write_zeroes_sectors value
a little further down the callchain, so don't bother to setup a limit
in decide_on_discard_support.
