Subject: [GIT PULL] Smack patches for 6.9

Hello Linus,

Here is the Smack pull request for v6.9.

There are 6 patches. One is a simple refactoring to remove
code duplication. The other five, from Roberto Sassu, correct
the in-memory inode initialization path used by ramfs in Smack.
This is necessary for ramfs to correctly handle directory label
transmutation.

All has been in the next branch and pass all tests.

The following changes since commit 6613476e225e090cc9aad49be7fa504e290dd33d:

  Linux 6.8-rc1 (2024-01-21 14:11:32 -0800)
