Wong: XFS - 2019 Development Retrospective

XFS filesystem maintainer Darrick Wong summarizesthe significant XFS developments from the last year. "The year2038 poses a special problem for Linux -- any signed 32-bit seconds counterwill overflow back to 1901. Work is underway in the kernel to extend all ofthose counters to support 64-bit counters fully. In 2020, we will beginwork on extending XFS's metadata (primarily inode timestamps and quotaexpiration timer) to support timestamps out to the year 2486. It should bepossible to upgrade to existing V5 filesystems."
