[Bug 2062556] Re: [Ubuntu-24.04] Hugepage memory is not getting released even after destroying the guest!
Many thanks for your confirmation Kowshik Jois. With that I'm updating the tags accordingly (and set them to verification done). ** Tags removed: verification-needed-noble-linux ** Tags added: verification-done-noble-linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2062556 Title: [Ubuntu-24.04] Hugepage memory is not getting released even after destroying the guest!

[Bug 2062556] Re: [Ubuntu-24.04] Hugepage memory is not getting released even after destroying the guest!
This bug is awaiting verification that the linux/6.8.0-32.32 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux' to 'verification-done-noble-linux'. If the problem still exists, change the tag 'verification-needed-noble- linux' to 'verification-failed-noble-linux'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you! ** Tags added: kernel-spammed-noble-linux-v2 verification-needed-noble-linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2062556 Title: [Ubuntu-24.04] Hugepage memory is not getting released even after destroying the guest!

[Bug 2062556] Re: [Ubuntu-24.04] Hugepage memory is not getting released even after destroying the guest!
I just had a look at noble's master-next tree:
$ git remote get-url origin
git://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/noble
$ git branch
* master-next
and found that commit 19c1ceeca8ed is already applied:
$ git log --oneline | grep -n "block: Fix page refcounts for unaligned buffers
in __bio_release_pages"
300:19c1ceeca8ed block: Fix page refcounts for unaligned buffers in
__bio_release_pages()
but not yet tagged with (incl. in) any version:
$ git tag --contains 19c1ceeca8ed
$
This is probably because it just came in via upstream stable updates:
$ git show 19c1ceeca8ed | sed '/^diff --git/q'
commit 19c1ceeca8ed31d207859e659482ee83ea1959f5

And since the lastest tagged Ubuntu kernel version in master-next is:
Ubuntu-6.8.0-31.31
$ git log --oneline | grep -n $(git describe --tags --abbrev=0)
1170:7fdb45c9bbbc (tag: Ubuntu-6.8.0-31.31) UBUNTU: Ubuntu-6.8.0-31.31
commit 19c1ceeca8ed will be automatically part of the next/upcoming
Ubuntu kernel (> Ubuntu-6.8.0-31.31).
With that I'm updating the status of this bug to Fix Committed.
