Each time a file in policy, that is already opened for write, is opened for read, an open-writers integrity violation audit message is emitted and a violation record is added to the IMA measurement list. 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.
