Formatting sd-cards does not trigger "change" uevents. As a result clients
using udev API don't get any updates afterwards and get outdated information
about the device.
Include mmcblk* in a match for watch option assignment.
Persistent memory devices can be exposed as block devices as /dev/pmemN
and /dev/pmemNs. pmemN is the raw device and is byte-addressable from
within the kernel and when mmapped by applications from a DAX-mounted
file system. pmemNs has the block translation table (BTT) layered on top,
offering atomic sector/block access. Both pmemN and pmemNs are expected
to contain file systems.
blkid(8) and lsblk(8) seem to correctly report on pmemN and pmemNs.
systemd v219 will populate /dev/disk/by-uuid/ when, for example, mkfs is
used on pmem, but systemd v228 does not.
Add pmem to the whitelist.
