This occurs even if a ToMToU violation has already been recorded. Limit the number of ToMToU integrity violations per file open for read. Note: The IMA_MAY_EMIT_TOMTOU atomic flag must be set from the reader side based on policy. This may result in a per file open for read ToMToU violation. Since IMA_MUST_MEASURE is only used for violations, rename the atomic IMA_MUST_MEASURE flag to IMA_MAY_EMIT_TOMTOU.

This occurs even if an open-writers violation has already been recorded. Limit the number of open-writers integrity violations for an existing file open for write to one. After the existing file open for write closes (__fput), subsequent open-writers integrity violations may be emitted.
