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.

An Alternative exFAT Linux File-System Driver Based On Samsung's sdFAT

While the upcoming Linux 5.4 kernel cycle is finally bringing a driver for Microsoft exFAT file-system read/write support, it's dated on an old Samsung code drop that has seen little public work over the years. Since queued for staging-next, there has been a big uptick in clean-ups and other activity, but there also exists another alternative out-of-tree exFAT Linux driver.

EROFS Is Graduating From Staging In Linux 5.4

Linux 5.4 will be a big kernel on the file-system front as in addition to introducing the new VirtIO-FS and exFAT file-system support, Huawei's EROFS file-system will be graduating from staging.

Improved Fscrypt File Encryption Handling Aims For Linux 5.4

Fscrypt is the common Linux kernel framework leveraged by the likes of the EXT4, F2FS, and UBIFS file-systems for providing native encryption support. While that Fscrypt-based file encryption has been part of the kernel for several releases now, there's been some shortcomings in how the encryption keys are handled but that should be cleared up for the upcoming Linux 5.4 cycle.

F2FS Case-Insensitive Support Is Pending Ahead Of The Linux 5.4 Kernel

EXT4 set off the new trend for opt-in, per-directory case-insensitive file/folder support on Linux systems. EXT4 picked up that optional case-insensitive support for Linux 5.2 while the for Linux 5.4 kernel cycle the Flash-Friendly File-System (F2FS) is set to receive similar support.

EROFS-Utils Adds LZ4 Compression Bits, Finally Has A README

While initially the user-space utility for Huawei's EROFS file-system was not publicly available, it came last November and this past April they began rewriting these EROFS user-space bits. Fortunately, since then they have done a better job of keeping EROFS-utils up-to-date against their latest kernel module changes for this read-only file-system.

IO_uring Gets A Huge Performance Fix - Up To 755x Improvement

IO_uring is designed to deliver fast and efficient I/O operations thanks to a re-designed interface introduced in Linux 5.1 with various efficiency improvements compared to the kernel's existing asynchronous I/O code. But it turns out there was a big bottleneck within the current IO_uring code up until now.
