From f4f9dd6eb3b81f2cb79aa3c41fd4d131cca91b6c Mon Sep 17 00:00:00 2001 From: Justin Eno Date: Tue, 27 Jan 2015 14:23:20 -0800 Subject: [PATCH] Better accommodate random writes larger than blockalign fill_io_u() fails prematurely if the randomly-chosen offset satisfies blockalign but not min_bs, i.e., the offset lies too near the end of the target region. This change honors both parameters.
