From 0f9248cf1e22333b2a0458540aafb1ad3b2b3337 Mon Sep 17 00:00:00 2001 From: Javier González Date: Fri, 13 Oct 2017 14:46:24 +0200 Subject: lightnvm: pblk: remove redundant check on read path MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A partial read I/O in pblk is an I/O where some sectors reside in the write buffer in main memory and some are persisted on the device. Such an I/O must at least contain 2 lbas, therefore checking for the case where a single lba is mapped is not necessary.
