RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
Currently if we want to find the devices which is added to a btrfs filesystem, the only way is use blkid and compare the UUID. It is helpful if there is a API used to show the relationship between btrfs filesystem and devices.


Version-Release number of selected component (if applicable):
libguestfs-1.28.1-1.10.el7


How reproducible:
100%


Steps to Reproduce:
1.
2.

Expected results:


Additional info:

Added with
https://github.com/libguestfs/libguestfs/commit/e3d429d37d882d06f25991ea0076d0c3bef44e80
which is in libguestfs >= 1.33.29.

Fixed upstream, thanks Pino.  However new APIs for speculative
non-customer features are not RHEL 7.3 material, so I have
kicked this to RHEL 7.4 when undoubtedly we'll want to do yet
another rebase, and that will pick up this fix.

Verified with package:
libguestfs-1.36.3-1.el7.x86_64

Steps:
1. $ guestfish
><fs> scratch 1G
><fs> run
><fs> part-init /dev/sda gpt
><fs> part-add /dev/sda p 34 600000
><fs> part-add /dev/sda p 600001 1200000
><fs> part-add /dev/sda p 1200001 2097118
><fs> mkfs ext4 /dev/sda2
><fs> mkfs-btrfs "/dev/sda1 /dev/sda3"
><fs> list-filesystems
/dev/sda1: btrfs
/dev/sda2: ext4
/dev/sda3: btrfs
><fs> btrfs-filesystem-show /dev/sda1
/dev/sda1
/dev/sda3

Actual results:
The API lists all the associated devices of a btrfs filesystem. So Verified.

Additional info:
Pino provided the test steps. Thanks.
