From b21b03ca624b89caeedfe58430cea4b40317d39f Mon Sep 17 00:00:00 2001 From: Sergey Bugaev Date: Wed, 4 Dec 2024 14:34:02 +0300 Subject: libstore: Fix zero store writes We discard any written data, but we still need to set *amount. Not doing that is undefined behavior, and causes the write to appear to fail. This is the cause of a libzstd test failure on GNU/Hurd in particular.
