[ Upstream commit e044374a8a0a99e46f4e6d6751d3042b6d9cc12e ] It is not clear that IMA should be nested at all, but as long is it measures files both on overlayfs and on underlying fs, we need to annotate the iint mutex to avoid lockdep false positives related to IMA + overlayfs, same as overlayfs annotates the inode mutex.
