Help text

This option adds support for in-kernel verification of fs-verity builtin signatures.

Please take great care before using this feature. It is not the only way to do signatures with fs-verity, and the alternatives (such as userspace signature verification, and IMA appraisal) can be much better. For details about the limitations of this feature, see Documentation/filesystems/fsverity.rst.

If unsure, say N.
