From a72bfd4dea053bb8e2233902c3f1893ef5485802 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Sat, 26 Sep 2009 00:07:46 +0200 Subject: writeback: pass in super_block to bdi_start_writeback() Sometimes we only want to write pages from a specific super_block, so allow that to be passed in. This fixes a problem with commit 56a131dcf7ed36c3c6e36bea448b674ea85ed5bb causing writeback on all super_blocks on a bdi, where we only really want to sync a specific sb from writeback_inodes_sb().
