Btrfs Async Discard Support Looks To Be Ready For Linux 5.6

After months of work by Facebook engineers, it looks like the new async discard support for Btrfs is ready for the upcoming Linux 5.6 cycle as a win for this Linux file-system on solid-state storage making use of TRIM/DISCARD functionality.

Linus Torvalds Doesn't Recommend Using ZFS On Linux

Linux kernel creator Linus Torvalds doesn't recommend using ZFS On Linux at least until Oracle were to re-license the code to make it friendly for mainline inclusion. But even then he doesn't seem turned on by the ZFS features or general performance.

FSCRYPT's Inline Encryption Support Updated For Possible Inclusion In Linux 5.6

Back in October we reported on work done by Google on FSCRYPT inline encryption support for allowing the Linux file-system encryption framework to handle the encrypt/decrypt more optimally for modern mobile SoCs with inline encryption hardware. It's looking like that work might be ready to go now for Linux 5.6 after missing out on the 5.5 cycle.

Oracle Talks Up Recent Features For XFS + Some File-System Improvements On The Horizon

Oracle's had quite the file-system history and looking ahead to 2020 they appear committed to the XFS boat on the Linux front. Oracle retains control over the upstream ZFS file-system and could push for better Linux integration of that file-system plus they formerly employed Btrfs creator Chris Mason during its infancy. But they also employ lead XFS maintainer Darrick Wong and in keeping in-line with Red Hat Enterprise Linux defaults embrace that as their primary file-system for Oracle Linux.

GRUB Now Supports Btrfs 3/4-Copy RAID1 Profiles (RAID1C3 / RAID1C4 On Linux 5.5+)

When it comes to the storage/file-system changes with the in-development Linux 5.5 kernel one of the most prominent end-user-facing changes is more robust RAID1 for Btrfs with the ability to have three or four copies of the data rather than just two copies, should data safety be of utmost importance and concerned over the possibility of two disks in an array failing.

EXT4 On Linux 5.5 To Support Encryption On Smaller Block Sizes

For the past four years going back to Linux 4.4 has been EXT4 native file-system encryption making use of the kernel's FSCRYPT framework that is shared between several file-systems. That support has continued to improve with time and with Linux 5.5 another limitation will be dropped.

F2FS File-System Seeing LZO/LZ4 Compression Support

Similar to the transparent file-system compression that has been available on the likes of Btrfs and ZFS for years, the Flash-Friendly File-System (F2FS) is also in the process of receiving native compression support.
