From: Danilo Krummrich <[email protected]> idr_init_base(), implemented by commit 6ce711f27500 ("idr: Make 1-based IDRs more efficient"), let us set an arbitrary base other than idr_init(), which uses base 0.
Since, for this IDR, no ID < 1 is ever requested, using idr_init_base(&idr, 1) avoids unnecessary tree walks.
