With Btrfs continuing to see new adoption by various enterprises, Linux distributions like Fedora Workstation/Cloud and SUSE/openSUSE embracing it, and there continuing to be nice upstream improvements to this file-system driver, Btrfs continues on a nice trajectory in 2021.
Sent in on Monday were the main set of feature updates for the Btrfs file-system code with the in-development Linux 5.14 kernel. There isn't anything revolutionary with this pull request but just a pleasant assortment of various fixes and improvements for this "next-generation" Linux file-system.

Linux 5.14 Drops Its Legacy IDE Code
Linux 5.14 has cleared out its legacy IDE code from the kernel that means dropping more than forty thousand lines of code.
Linux's legacy IDE driver code has been deprecated since 2019 and planned for removal in 2021. This is about clearing out the legacy IDE code while IDE driver support remains available via the more modern libata-based code in the kernel. This legacy code is what was commonly associated with the older /dev/hdX devices. Most systems and Linux users have likely not used this legacy code in more than one decade.
