Subject: [PATCH] loongarch: wire up memfd_secret system call
Date: Fri, 9 Jan 2026 13:10:51 +0800 [thread overview]
Message-ID: <20260109051054.188030-1-fearyncess@aosc.io> (raw)
From: "Lain \"Fearyncess\" Yang" <fearyncess@aosc.io>
LoongArch supports ARCH_HAS_SET_DIRECT_MAP, therefore wire up the
memfd_secret system call, which depends on it.
Signed-off-by: Lain "Fearyncess" Yang <fearyncess@aosc.io>
