Link to package [[https://launchpad.net/ubuntu/+source/libtracefs|libtracefs]]

[Rationale]

libtracefs is a new dependency of ndctl which was introduced by upstream in version 76:

https://github.com/pmem/ndctl/commit/68c72f36e

Since ndctl is in main and libtracefs seems to enable useful features, let's promote it to main and fix the component mismathc.

It would be great and useful to community/processes to have the package libtracefs in Ubuntu main, but there is no hard deadline, hopefully before Lunar release.

[Security]

Nothing was found in the CVE database:

https://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=libtracefs

Also nothing was found in the OSS security mailing list archive.

No CVE in the Ubuntu security tracker:

https://ubuntu.com/security/cves?package=libtracefs

Nor in the Debian security tracker:

https://security-tracker.debian.org/tracker/source-package/libtracefs

- no executables in `/sbin` and `/usr/sbin`
- Package does not install services, timers or recurring jobs
- Packages does not open privileged ports (ports < 1024)
- Packages does not contain extensions to security-sensitive software (filters, scanners, plugins, UI skins, ...)

[Quality assurance - function/usage]

- The package works well right after install

[Quality assurance - maintenance]

- The package is maintained well in Debian/Ubuntu/Upstream and does not have too many, long-term & critical, open bugs
- Ubuntu https://bugs.launchpad.net/ubuntu/+source/libtracefs/+bug
- Debian https://bugs.debian.org/cgi-bin/pkgreport.cgi?src=libtracefs
- The package does not deal with exotic hardware we cannot support

[Quality assurance - testing]

- The package runs a test suite on build time, if it fails it makes the build fail, link to build log:

https://launchpadlibrarian.net/646632616/buildlog_ubuntu-lunar-amd64.libtracefs_1.6.4-1_BUILDING.txt.gz

The package does not implement any DEP-8 test right now. I am adding some here:

https://code.launchpad.net/~lucaskanashiro/ubuntu/+source/libtracefs/+git/libtracefs/+merge/438414

Once it is approved it will be uploaded to Lunar and forwarded to Debian.

Since there is no autopkgtest run against the version in the archive, there is no failure.
