[$] XArray and the mainline

Post Syndicated from jake original https://lwn.net/Articles/757342/rss

The XArray data structure was the topic of
the final filesystem track session at the 2018 Linux Storage, Filesystem,
and Memory-Management Summit (LSFMM). XArray is a new API for the kernel’s
radix-tree data structure; the session was
led by Matthew Wilcox, who created XArray. When asked by Dave Chinner if
the session was intended to be a live review of the patches, Wilcox
admitted with a grin that it might be “the only way to get a review on this
damn patch set”.
