F2FS With Linux 4.4 Brings Better Stability/Performance For In-Memory Extent Caches

Written by Michael Larabel in Linux Storage on 5 November 2015 at 03:23 PM EST. 9 Comments
Jaegeuk Kim sent in the Flash-Friendly File-System (F2FS) updates today for targeting the Linux 4.4 kernel.

Most of the F2FS patches for Linux 4.4 are for enhancing the stability and performance of the file-system's in-memory extent caches feature. There's also new ioctls to test behavior during power failures and checkpoints, a new background_gc=sync option to do garbage collection synchronously, periodic checkpoints support, and a number of bug-fixes.

More details on this round of F2FS updates can be found via the mailing list pull request>
