Subject: [PATCH v2 0/2] char: misc: improve test and dynamic allocation
Date: Fri, 07 Mar 2025 11:39:26 -0300 [thread overview]
Message-ID: <20250307-misc-dynrange-v2-0-6fe19032ef76@igalia.com> (raw)
This includes a change that prevents dynamic allocation from using a minor
number that belongs to the historically static reserved range, which is
still used by some drivers.
It also improves the test, including a lot of corner cases, specially ones
that would fail before past fixes.
