GFS2: Pull request (merge window)
Hi,
Please consider pulling the following changes:
The main feature this time is the new Orlov allocator and the patches leading up to it which allow us to allocate new inodes from their own allocation context, rather than borrowing that of their parent directory. It is this change which then allows us to choose a different location for subdirectories when required. This works exactly as per the ext3 implementation from the users point of view.
In addition to that, we've got a speed up in gfs2_rbm_from_block() from Bob Peterson, three locking related improvements from Dave Teigland plus a selection of smaller bug fixes and clean ups.
The following changes since commit 0e4a43ed08e2f44aa7b96aa95d0a540d675483e1:
