Subject: [PATCH v3 9/9] scsi: ufs: exynos: Select CONFIG_BLK_SUB_PAGE_SEGMENTS for lage page sizes
Date: Wed, 18 Jan 2023 14:54:47 -0800 [thread overview]
Message-ID: <20230118225447.2809787-10-bvanassche@acm.org> (raw)
In-Reply-To: <20230118225447.2809787-1-bvanassche@acm.org>
Since the maximum segment size supported by the Exynos controller is 4
KiB, this controller needs CONFIG_BLK_SUB_PAGE_SEGMENTS if the page size
exceeds 4 KiB.
