Subject: linux-next: build failure after merge of the vfs-brauner tree

Hi all,

After merging the vfs-brauner tree, today's linux-next build (x86_64
allmodconfig) failed like this:

Caused by commit

  1602bad16d7d ("vfs: expose delegation support to userland")

I have used the vfs-brauner tree from next-20251114 for today.
