Hi all, Here are some minor fixes and two new e2fsprogs tools! The first patch fixes a bunch of compiler warnings. The first tool, e2info, uses the proposed ext4 geometry ioctl to query a mounted ext4 filesystem for geometry information and prints it. The second tool, e2spacey, uses the proposed GETFSMAP and ext4 ioctls to find all the free space on a mounted filesystem to display a histogram of extent sizes, or optionally how much free space can be found in each flexbg. (Note: the xfs_io tool can be used for general getfsmap queries on ext4 filesystems.) If you want to go play with these tools, you can grab the source from my git repo[1]. You'll need the patches on mailing list, or my djwong-devel kernel tree[2]. This is a tremendous way to eat your data! --D [1] https://git.kernel.org/cgit/linux/kernel/git/djwong/e2fsprogs.git/log/?h=djwong-devel [2] https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git/log/?h=djwong-devel
