1.2 Cleanup
1.2.1 Replace current_time and current_time_sec
1.2.2 Fill in right granularities
1.2.3 Fill in right ranges
1.3 Test
1.3.1 Test time written on disk and in memory are same
1.3.2 Test time ranges beyond y2038
1.3.3 Test time granularities are what the fs needs
1.3.4 Test time ranges supported are same as what fs reports
1.3.5 Perf tests
1.3.6 Test to check i_dirty_* flags are updating correctly
1.3.7 Test to check with different mount options like lazy atime etc.
1.4 Kernel tasks to transition vfs to use 64 bit times
1.4.1 Infrastructure patches for vfs_time approach
1.4.2 Infrastructure patch for vfs granularity fields
1.4.3 Change each fs to use vfs time patches
1.4.4 Change vfs to use timespec64
1.4.5 Expose fs granularities
1.4.6 Expose fs ranges
1.4.7 Add vfs policy for handling wrong ranges and granularity
1.4.8 Stat and utime api changes
1.5 Runtime library
1.5.1 Make changes in one library
1.5.2 Make it part of some userspace and run it
