Titre: What's new in Linux 3.8
Posté par: djohnston le 22 février 2013 à 21:57:26
Here's the part I find interesting:

Citer
Linux now supports (http://git.kernel.org/linus/a13eea6bd9ee62ceacfc5243d54c84396bc86cb4) F2FS (Flash-Friendly File System), a filesystem that was introduced (http://www.h-online.com/news/item/Samsung-contributes-F2FS-NAND-filesystem-to-Linux-1725277.html) by Samsung developers in October. It is designed for flash storage media that uses a more basic Flash Translation Layer (http://en.wikipedia.org/wiki/Flash_Translation_Layer) (FTL) than SSDs for desktop PCs and servers – for example USB flash drives, memory cards and the storage media that is used in cameras, tablets and smartphones.

F2FS is a Log-structured File System (http://en.wikipedia.org/wiki/Log-structured_file_system) (LFS) and progressively fills up storage media from the beginning; only once it has reached the end will it return to the beginning and use any areas that may have been deallocated in the meantime. Like Btrfs, F2FS uses Copy-on-Write (http://en.wikipedia.org/wiki/Copy-on-write) (COW) to sequentially fill storage devices; this provides a certain robustness. Unlike Btrfs and Ext4, F2FS does not attempt to prevent data fragmentation; very short access times mean that fragmentation is not an issue with flash storage media. The userspace tools for formatting F2FS drives are available at kernel.org (http://git.kernel.org/?p=linux/kernel/git/jaegeuk/f2fs-tools.git;a=summary).

It's nice to know Linux is on top of all the new graphics drivers, Intel HD 4000
included.    Still I think my ext3 plus extent idea is longlasting.   All these new
filesystems and features are going to tax the fsarchiver program a bit. 

Thanks for the news post.
