Subject: [PATCH 09/12] tools/nolibc: use a custom struct timespec
Date: Wed, 29 Oct 2025 17:02:59 +0100	[thread overview]
Message-ID: <20251029-nolibc-uapi-types-v1-9-e79de3b215d8@weissschuh.net> (raw)
In-Reply-To: <20251029-nolibc-uapi-types-v1-0-e79de3b215d8@weissschuh.net>

A custom 'struct timespec' will be necessary for 64-bit time types on
32-bit architectures. <linux/time.h> will define other time-related
types in terms of the custom definition.
