From 6abc4f36b38aa6be3c7e4b89e2997e5006e40b37 Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Tue, 1 Jun 2021 07:01:44 -0700 Subject: [PATCH] default flush to use block device nsid Kernel 5.13 added checks to ensure the ioctl path can't be abused to access a different namespace than the one user space has permission to open. This unfortunately breaks the all-nsid flush usage, so user tooling needs to default to the device's namespace id.
