Microsoft's open after exFAT technology and actively adding it to the Linux kernel, Linux Kernel 5.4 has brought to the exFAT file system of preliminary support . Now, improvements based on early code, the new exFAT file system driver will be installed in Linux Kernel 5.7 provides.
Various Linux Kernel exFAT driver 5.4 Samsung developed version a few years ago, and during this period based on made other improvements. But over the years, Samsung has also been internal use and improve exFAT Linux driver, it will also be sold as part of the equipment. Since Microsoft Open Specification exFAT last year, Samsung has been working to provide improved upstream file system driver, and use their Android devices have been applied upstream kernel code base.
In the past few months, Samsung driver code was a major revision, the pursuit of exFAT driver steady development since the line has also been proceeding code cleanup.
▲ exFAT is currently mainly used for consumer-grade U disk and memory card
Samsung's latest exFAT driver is ready to enter the VFS next-generation warehouse , said to the driver of the state better than the old version, and is actively maintained by Samsung engineers will continue to move forward. It will go directly to the core part of the file system.
Existing driver has not been removed, but in Kconfig configuration, the two exFAT drivers belong to a mutually exclusive relationship, and therefore can not be activated both from the same kernel. Probably once the new exFAT driver passed the verification, the old driver will likely to be removed from the kernel source tree. New implementation located fs / exfat and use EXFAT_FS Kconfig switch constructed.
