Subject[PATCH v3] checksyscalls: Ignore fstat to silence build warning on LoongArch
Date
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]

Suggested-by: WANG Xuerui <kernel@xen0n.name>
