From 3351bb4ff5cd2ef4d8f7cfb87451f021bcccb37e Mon Sep 17 00:00:00 2001 From: Andrew Clayton Date: Sat, 19 Nov 2022 23:58:51 +0000 Subject: Isolation: Remove the syscall(SYS_getpid) wrapper. When using SYS_clone we used the getpid kernel system call directly via syscall(SYS_getpid) to avoid issues with cached pids. However since we are now only using fork(2) (+ unshare(2) for namespaces) we no longer need to call the kernel getpid directly as the fork(2) will ensure the cached pid is invalidated.
