XFS filesystem maintainer Darrick Wong summarizes the significant XFS developments from the last year. "The year 2038 poses a special problem for Linux -- any signed 32-bit seconds counter will overflow back to 1901. Work is underway in the kernel to extend all of those counters to support 64-bit counters fully. In 2020, we will begin work on extending XFS's metadata (primarily inode timestamps and quota expiration timer) to support timestamps out to the year 2486. It should be possible to upgrade to existing V5 filesystems."
