Subject: [PATCH v2] checksyscalls: Ignore fstat to silence build warning on LoongArch
Date:   Tue, 30 Aug 2022 10:50:00 +0800
Message-Id: <1661827800-8463-1-git-send-email-yangtiezhu@loongson.cn>
Precedence: bulk

fstat is replaced by statx on the new architecture, so an exception
is added to the checksyscalls script to silence the following build
warning on LoongArch:

  CALL    scripts/checksyscalls.sh
<stdin>:569:2: warning: #warning syscall fstat not implemented [-Wcpp]
