This syscall is issued transparently by the linux kernel when timing-related syscalls (such as nanosleep) get interrupted, for example because of SIGSTOP. Signed-off-by: Patrick Roy <roypat@amazon.co.uk>
This syscall is inserted at runtime by the linux kernel, and thus not actually present in our binary. The static analysis tool thus correctly marks it as unused. Introduce an allowlist of syscalls that are ignored by the static analysis tool to deal with this. Signed-off-by: Patrick Roy <roypat@amazon.co.uk>
