Subject: [PATCH 24/33] Generate a zero-length signature for symlinks
45afda
45afda
The fsverity utility follows the symlink when generating a signature.
45afda
Since we don't want to sign the same file twice, we need to skip these
45afda
links, and instead just generate a dummy zero-length signature here.
