/* ima_iint_find_insert_get - get the iint associated with an inode
 *
 * Most insertions are done at inode_alloc, except those allocated
 * before late_initcall. When the iint does not exist, allocate it,
 * initialize and insert it, and increment the iint refcount.
 *
 * (Can't initialize at security_initcall before any inodes are
 * allocated, got to wait at least until proc_init.)
 *
 *  Return the iint.
