SubjectRE: [PATCH 8/9] select/restart_block: Convert poll's timeout to u64
Date
From: Dmitry Safonov
> Sent: 09 September 2019 11:24
>
> All preparations have been done - now poll() can set u64 timeout in
> restart_block. It allows to do the next step - unifying all timeouts in
> restart_block and provide ptrace() API to read it.
