From c3c532061e46156e8aab1268f38d66cfb63aeb2d Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 22 Apr 2010 11:37:01 +0200 Subject: bdi: add helper function for doing init and register of a bdi for a file system Pretty trivial helper, just sets up the bdi and registers it. An atomic sequence count is used to ensure that the registered sysfs names are unique.
