IMA memory hog

"This work eliminates almost all of the memory waste, but at the cost of growing the inode structure slightly. That does not sit well with everybody, especially, it seems, those developers who feel that IMA should not exist in the first place."

Well, looking at the patches, it should be said that the inode structure growth is dependent on CONFIG_IMA, thus, if IMA is not enabled, the inode structure doesn't grow at all.
