But this does not initialize the eventfs_inode list_heads. If\nthe eventfs_create_dir() fails due to memory pressure, it will call\nfree_ei() before it initialized the lists, and that checks to make sure\nthe eventfs_inode has no children. But because the list wasn't\ninitialized, it will give a false warning.\n\nFix it by moving the list initialization into init_ei().\n\n[ Rewrote change log
