Subject: memfd: export memfd_{add,get}_seals()
Date: Fri, 23 Jan 2026 10:58:50 +0100

Patch series "mm: memfd_luo: preserve file seals".

This series adds support for preserving file seals when preserving a memfd
using LUO.  Patch 1 exports some memfd seal manipulation functions and
patch 2 adds support for preserving them.  Since it makes changes to the
serialized data structure for memfd, it also bumps the version number.


This patch (of 2):

Support for preserving file seals will be added to memfd preservation
using the Live Update Orchestrator (LUO).  Export memfd_{add,get}_seals)()
so memfd_luo can use them to manipulate the seals.
