Subject: [PATCH 1/1] rules: block: add support for pmem devices (#3683)
|
||
|
|
|
||
|
|
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.
|
||
|
|
(cherry picked from commit f3bc4ccc2edf5ad2a99d6ba2795b9999fe76c3df)
