Hello everyone,
I've finally put out my large blocksize work. This includes a number of
changes:
* Support for blocksizes larger than 4K
* Support for different leaf and node sizes
* Allocations are counted in bytes instead of blocks (required because
there is no one block size).
* New code to track free extents, both metadata and data block groups
are cached now.
* New defrag code
This involves a number of disk format changes, and I've got a few format
changes pending. I've put them into two new HG trees:
http://oss.oracle.com/mercurial/mason/btrfs-unstable
http://oss.oracle.com/mercurial/mason/btrfs-progs-unstable
So far it has only been tested on x86-64. I expect a number of minor
problems on i386.
-chris
