Linus Torvalds 3be134e515 libnvdimm for 4.10 ... * Dynamic label support: To date namespace label support has been limited to disambiguating cases where PMEM (direct load/store) and BLK (mmio aperture) accessed-capacity alias on the same DIMM. Since 4.9 added support for multiple namespaces per PMEM-region there is value to support namespace labels even in the non-aliasing case. The presence of a valid namespace index block force-enables label support when the kernel would otherwise rely on region boundaries, and permits the region to be sub-divided. * Handle media errors in namespace metadata: Complement the error handling for media errors in namespace data areas with support for clearing errors on writes, and downgrading potential machine-check exceptions to simple i/o errors on read. * Device-DAX region attributes: Add 'align', 'id', and 'size' as attributes for device-dax regions. In particular this enables userspace tooling to generically size memory mapping and i/o operations. Prevent userspace from growing assumptions / dependencies about the parent device topology for a dax region. A libnvdimm namespace may not always be the parent device of a dax region. * Various cleanups and small fixes. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJYVxRcAAoJEB7SkWpmfYgCSnoQAKNs7IJRtGqKFCkMB5VDAW79 Lifi35Hqm+mfFaLMIyRoKJMnhXKQBsthfcHZIy5t63kDWEV/tJ+riZ+m2Ibz4GPE AUn07jxge2q9v0RwMylqpZ/EHyaK/xD1z0+SdIwVF2VaEDoVdnmu2WEqjuir/lfM t70B/YoWLg6CcHeTzaV5vdxlRKyG4pzOV3UzPlYLROr3wFJBHD88j/4zcGy3F1ue DpzGThhtEQXZUZCJLp54E0ch7V2cz/DNUDYwsjbCZrdYYmUJFqjZQxNyftn28aEJ HI/BERXLhm2HF2qRqC+0C1lJmUylYk4wXUGco+b/u1GYN59eFe/JT3dJgxEHFKL2 nVOUmR8XsRE6gkFWQGcFesRjjI1Rqz2Wgql7oqkSL9grGOwY4rvKX0LhJxgvfuZ0 Itb5h0dMFUriAP0DaaJFMYfANIOx+mqr4RxDMwP5ZADku6+Ga0LXxvcBt06K/mYO /zLo27MhsuuFy/odXm1A21OjFiH2pM3pSCaytKvDjy7DwzgE7ZzXmixXQ7j8YVp6 OtLYzMjIt8nt4xh0hmav5tb0r9l6mgNqlifacMC9lEM/7SDAiBXXBLuQngJN/j0s iXllBk0pYVWibf3VcD6oY+qKdmBWvXxPjgj1lHE6j9A7Gw2jwIt/W2NWzV94nKmC f6d+faHiRokqyVhdgfx3 =YWfP -----END PGP SIGNATURE----- Merge tag 'libnvdimm-for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm updates from Dan Williams: "The libnvdimm pull request is relatively small this time around due to some development topics being deferred to 4.11. As for this pull request the bulk of it has been in -next for several releases leading to one late fix being added (commit 868f036fee ("libnvdimm: fix mishandled nvdimm_clear_poison() return value")). It has received a build success notification from the 0day-kbuild robot and passes the latest libnvdimm unit tests.

Since 4.9 added support for multiple namespaces per PMEM-region there is value to support namespace labels even in the non-aliasing case. The presence of a valid namespace index block force-enables label support when the kernel would otherwise rely on region boundaries, and permits the region to be sub-divided. - Handle media errors in namespace metadata: Complement the error handling for media errors in namespace data areas with support for clearing errors on writes, and downgrading potential machine-check exceptions to simple i/o errors on read. - Device-DAX region attributes: Add 'align', 'id', and 'size' as attributes for device-dax regions.
