Subject: [ndctl PATCH v2 18/26] ndctl/test: Exercise sub-section sized namespace creation/deletion
Date: Sat, 27 Jul 2019 14:40:58 -0700 [thread overview]
Message-ID: <156426365799.531577.4076109633772194960.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <156426356088.531577.14828880045306313118.stgit@dwillia2-desk3.amr.corp.intel.com>
For kernels that have removed the section-aligned namespace constraint
validate that multiple namespaces can be created / deleted that collide
within a given section.
While this test acts on the ACPI.NFIT bus it is not marked "destructive"
because it only operates in available capacity and marks each namespace
created with a unique volume name ("subsection-test").
