Subject: [PATCH] mm/mseal: use min/max in mseal_apply
Date: Sun,  3 May 2026 13:59:16 +0200	[thread overview]
Message-ID: <20260503115915.18680-3-thorsten.blum@linux.dev> (raw)

Use the type-checked min()/max() macros instead of MIN()/MAX(), which
are supposed to be used "for obvious constants only".
