F2FS File-System Shows Regressions On Linux 3.10

For the Flexible I/O Tester with one of the common test settings, the Linux 3.8/3.9 performance was the same but when running Linux 3.10-rc1 there is a noticeable slowdown in its performance.

The FS-Mark performance is mostly the same from this Intel SSD with F2FS between the Linux 3.8 and 3.10 kernels except for the four-threaded test scenario where the disk performance seems to decline on the latest development kernel.

The Dbench file-system test is noticeably slower on Linux 3.10-rc1 with F2FS on the solid-state drive than on earlier Linux kernels.
