From 2aea39eca6b68d6ae7eb545332df0695f56a3d3f Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Thu, 24 Apr 2014 09:49:52 +0900 Subject: f2fs: submit bio at the reclaim path If f2fs_write_data_page is called through the reclaim path, we should submit the bio right away. This patch resolves the following issue that Marc Dietrich reported. "It took me a while to bisect a problem which causes my ARM (tegra2) netbook to frequently stall for 5-10 seconds when I enable EXA acceleration (opentegra experimental ddx)." And this patch fixes that.
