From 79ded4de760eb4489893b3ef1f9966c486629849 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Matias=20Bj=C3=B8rling?= Date: Mon, 25 Nov 2019 11:40:34 +0800 Subject: [PATCH] lightnvm: pblk: fix incorrect min_write_pgs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit 8bbd45d02a118cbefdf4e1a6274bd965a6aa3c59 ] The calculation of pblk->min_write_pgs should only use the optimal write size attribute provided by the drive, it does not correlate to the memory page size of the system, which can be smaller or larger than the LBA size reported.
