Subject: [PATCH 03/10] drm: use idr_init_base() to initialize master->magic_map
Date: Fri, 1 Jul 2022 20:52:56 +0200 [thread overview]
Message-ID: <20220701185303.284082-4-dakr@redhat.com> (raw)
In-Reply-To: <20220701185303.284082-1-dakr@redhat.com>
From: Danilo Krummrich <dakr@redhat.com>
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/allocated, using
idr_init_base(&idr, 1) avoids unnecessary tree walks.
