Hello, this is the third revision of the patch series which converts all embedded occurences of struct backing_dev_info to use standalone dynamically allocated structures. This makes bdi handling unified across all bdi users and generally removes some boilerplate code from filesystems setting up their own bdi. It also allows us to remove some code from generic bdi implementation. The patches were only compile-tested for most filesystems (I've tested mounting only for NFS & btrfs) so fs maintainers please have a look whether the changes look sound to you. This series is based on top of bdi fixes that were merged into linux-block git tree into for-next branch. I have pushed out the result as a branch to git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs.git bdi Since all patches got reviewed by Christoph, can you please pick them up Jens? Thanks! Changes since v2: * Added Reviewed-by tags from Christoph Changes since v1: * Added some acks * Added further FUSE cleanup patch * Added removal of unused argument to bdi_register() * Fixed up some compilation failures spotted by 0-day testing Honza
