Subject: default flush to use block device nsid
X-Git-Tag: v1.15~61

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.
