2016-02-12 Thread Deepa Dinamani
Introduction This is a follow on to the series: https://lkml.org/lkml/2016/1/7/20 [1]. This is aimed at reaching a consensus on how to transition the vfs timestamps to use 64 bit time. This demonstrates three ways (2a, 2b and 2c) of solving this problem. Each of the proposals has its own cover
