Linux Patch Posted For Syncing The Kernel Code With Zstd 1.5.7

([Linux Kernel] 4 Hours Ago Zstd 1.5.7 For The Linux Kernel)


The Zstandard (Zstd) compression code sadly hasn't been regularly synced with the latest upstream Linux kernel sources but a patch posted this evening goes ahead and syncs the in-kernel Zstd code against the Zstd 1.5.7 state.

Nick Terrell of Meta/Facebook posted the patch for importing the upstream Zstd 1.5.7 source code into the Linux kernel. Besides bringing some performance improvements and other enhancements, Intel engineers have been desiring this in-kernel update to expose the Zstd APIs to allow QAT acceleration for speeding up the LZ match finding stage of Zstd. This in turn can yield additional performance benefits on Intel QAT-enabled hardware.

Benchmarks of Btrfs compression using Zstd with this newly-updated code shows a mix of speed-ups and some regressions across a range of compression and decompression tests.

Those interested in this long overdue sync of [1]Zstd 1.5.7 -- and in turn 1.5.4 through 1.5.6 too -- for the Linux kernel can see [2]this patch on the Linux kernel mailing list. Hopefully it manages to get upstreamed in the next kernel merge window.

New Linux Companies Hope To Get Rich Quick (#4)

The buzz surrounding Linux and Open Source during 1999 has produced a
large number of billionnaires. However, people who weren't employed by Red
Hat or VA Linux, or who didn't receive The Letter, are still poor. The
visionaries at The IPO Factory want to change all that.

As the name suggests, this company helps other businesses get off the
ground, secure investments from Venture Capitalists, and eventually hold
an IPO that exits the stratosphere. "You can think of us as meta-VCs," the
IPO Factory's founder said. "You provide the idea... and we do the rest.
If your company doesn't hold a successful IPO, you get your money back,
guaranteed!" He added quickly, "Of course, if you do undergo a billion
dollar IPO, we get to keep 25% of your stock."

The company's first customer, LinuxOne, has been a failure. "From now on
we're only going to service clients that actually have a viable product,"
an IPO Factory salesperson admitted. "Oh, and we've learned our lesson:
it's not a good idea to cut-and-paste large sections from Red Hat's S-1
filing."
