From 8bbd45d02a118cbefdf4e1a6274bd965a6aa3c59 Mon Sep 17 00:00:00 2001 From: Matias Bjørling Date: Tue, 9 Oct 2018 13:11:38 +0200 Subject: lightnvm: pblk: fix incorrect min_write_pgs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
