From: Jaegeuk Kim Date: Thu, 24 Apr 2014 00:49:52 +0000 (+0900) Subject: f2fs: submit bio at the reclaim path X-Git-Tag: v3.15.3~39 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fecb45f70819ed260fc801c27ef41bf573ee7739;p=thirdparty%2Fkernel%2Fstable.git f2fs: submit bio at the reclaim path commit 2aea39eca6b68d6ae7eb545332df0695f56a3d3f upstream. 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.
