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.

ZFS On Linux Has Figured Out A Way To Restore SIMD Support On Linux 5.0+

Those running ZFS On Linux (ZoL) on post-5.0 (and pre-5.0 supported LTS releases) have seen big performance hits to the ZFS encryption performance in particular. That came due to upstream breaking an interface used by ZFS On Linux and admittedly not caring about ZoL due to it being an out-of-tree user. But now several kernel releases later, a workaround has been devised.

EROFS Looking To Be Promoted Out Of Linux's Staging Area

Huawei's EROFS file-system has been part of the mainline Linux kernel for about one year albeit as part of the "staging" area until it's been proven stable and mature. Now with this file-system reportedly in use on "10+ millions of Huawei Android mobile phones", they are looking to have this file-system promoted out of staging.

SUSE Reworking Btrfs File-System's Locking Code

SUSE continues to back the Btrfs file-system and as part of that investing in new/improved functionality around this Linux file-system once billed as the competitor to ZFS. This week one of the SUSE developers sent out a set of patches implementing a new "DRW" lock and wiring that into the file-system driver.
