Subject: [GIT PULL] Confidential Computing: Attestation Updates for 7.0
Date: Sat, 14 Feb 2026 18:07:34 -0800	[thread overview]
Message-ID: <69912a6621326_2f4a1006b@dwillia2-mobl4.notmuch> (raw)

Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/devsec/tsm tags/tsm-for-7.0

...to receive a couple updates to the maximum buffer sizes supported for
the configfs-tsm-reports interface. Recall this interface is a common
transport that conveys the varied architecture specific launch
attestation reports for confidential VMs. 

They have appeared in linux-next with no known reports.
