associated with the new ID. ``u32 *nextid`` Pointer to an ID. ``unsigned long max`` The maximum ID to allocate (inclusive). ``gfp_t gfp`` Memory allocation flags. **Description** Allocates an unused ID in the range specified by **nextid** and **max**. Note that **max** is inclusive whereas the **end** parameter to idr_alloc() is exclusive. The new ID is assigned to **nextid** before the pointer is inserted into the IDR, so if **nextid** points into the object pointed to by **ptr**, a concurrent lookup will not find an uninitialised ID. The caller should provide their own locking to ensure that two concurrent modifications to the IDR are not possible. Read-only accesses to the IDR may be done under the RCU read lock or may exclude simultaneous writers. **Return** 0 if an ID was allocated, -ENOMEM if memory allocation failed, or -ENOSPC if no free IDs could be found.
