The macros are not y2038 safe. There is no plan to transition them into being y2038 safe. ktime_get_* api's can be used in their place. And, these are y2038 safe. Thanks to Arnd Bergmann for all the guidance and discussions. Patches 2-4 were mostly generated using coccinelle scripts. All filesystem timestamps use current_fs_time() for right granularity as mentioned in the respective commit texts of patches. This has a changed signature, renamed to current_time() and moved to the fs/inode.c. This series also serves as a preparatory series to transition vfs to 64 bit timestamps as outlined here: https://lkml.org/lkml/2016/2/12/104 . As per Linus's suggestion in https://lkml.org/lkml/2016/5/24/663 , all the inode timestamp changes have been squashed into a single patch. Also, current_time() now is used as a single generic vfs filesystem timestamp api. It also takes struct inode* as argument instead of struct super_block*. Posting all patches together in a bigger series so that the big picture is clear. As per the suggestion in https://lwn.net/Articles/672598/, CURRENT_TIME macro bug fixes are being handled in a series separate from transitioning vfs to use. Changes from v1: * Change current_fs_time(struct super_block *) to current_time(struct inode *) * Note that change to add time64_to_tm() is already part of John's kernel tree: https://lkml.org/lkml/2016/6/17/875 .
