I've posted a series at https://lore.kernel.org/lkml/20191130053030.7868-1-deepa.ker...@gmail.com/ I was able to get rid of all instances but it seemed like it would be easier for cifs to use timestamp_truncate() directly. If you really don't want it exported, I could find some other way of doing it. > BTW, could we *please* do something about fs/inode.c:update_time()? I mean, > sure, local variable shadows file-scope function, so it's legitimate C, but > this is not IOCCC and having a function called 'update_time' end with > return update_time(inode, time, flags); > is actively hostile towards casual readers... Added this to the series as well. -Deepa _______________________________________________ Y2038 mailing list Y2038@lists.linaro.org https://lists.linaro.org/mailman/listinfo/y2038
