It should have the same effect with the current dentry layout and default config options, but would keep the d_iname length in the 16-44 byte range instead of 16-76 byte as your patch does. Since all important fields are supposed to be kept in 32 bytes anyway, they are still either at the start or the end of a given cache line, but never cross two.
