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.
