From 17ee4f49ab2c802c7818fa71c4e7e351a7230b86 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Fri, 15 Jun 2007 13:10:37 +0200 Subject: [PATCH] splice: adjust balance_dirty_pages_ratelimited() call As we have potentially dirtied more than 1 page, we should indicate as such to the dirty page balancing. So call balance_dirty_pages_ratelimited_nr() and pass in the approximate number of pages we dirtied.
