From 352c912b0a525977a8e6fa1f87c15d9f71943642 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 24 Oct 2019 16:47:56 +0200 Subject: tsacct: add 64-bit btime field As there is only a 32-bit ac_btime field in taskstat and we should handle dates after the overflow, add a new field with the same information but 64-bit width that can hold a full time64_t.
