I've been working on a patchset to change how the inode->i_ctime is accessed in order to give us conditional, high-res timestamps for the ctime and mtime. struct timespec64 has unused bits in it that we can use to implement this. In order to do that however, we need to wrap all accesses of inode->i_ctime to ensure that bits used as flags are appropriately handled. This patchset first
