Subject: [ndctl PATCH v4 0/7] Improvements for namespace creation/interrogation
Date: Mon, 05 Aug 2019 16:28:41 -0700 [thread overview]
Message-ID: <156504772175.847544.11368833704527657055.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
Changes since v3 [1]:
- Drop the warning suppression for gcc9.1.1 the complains about taking
the address of packed structure members. This needs a rethink since
even the kernel's common ioctl payloads are defined to be packed. This
will require something like the kernel's (get_unaligned()) helpers.
(Jeff)
- Fix up a static analysis report introduced by "ndctl/dimm: Minimize
data-transfer for init-labels"

This trimmed version includes the extent support for label operations
which significantly speeds up common label operations like
'init-labels'. It also fixes up some surprising results from
'create-namespace' where it would fail even though available capacity is
present.
