Facebook雇用了多名Linux内核开发者，其中就包括了Btrfs文件系统的主要开发者Chris Mason。他在LSFMM峰会上分享了Facebook使用Linux内核的信息。Facebook的服务器使用了多个内核版本，大部分主机运行基于2.6.38的内核，还有部分服务器运行3.2稳定版内核（打了大约250 个补丁）和3.10 稳定版内核（打了约60 个补丁），大部分补丁与网络和跟踪子系统、以及内存管理有关。Facebook在与内核打交道中最频繁遇到的两个功能是稳定页（Stable pages）和完全公平调动I/O调度器。Btrfs实现了稳定页，而Facebook也雇用了完全公平调度器的开发者Jens Axboe。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
