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. Reported-by: Marc Dietrich <marvin24@gmx.de> Signed-off-by: Jaegeuk Kim <jaegeuk.kim@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
