Subject: [PATCH v2 1/2] linux-user: Add new flag VERIFY_NONE
Date: Sat, 22 Apr 2023 12:03:13 +0200 [thread overview]
Message-ID: <20230422100314.1650-2-thomas@t-8ch.de> (raw)
In-Reply-To: <20230422100314.1650-1-thomas@t-8ch.de>
This can be used to validate that an address range is mapped but without
being readable or writable.
It will be used by an updated implementation of mincore().
