Subject: [PATCH RFC v1 0/4] e2fsprogs: reserve more special inodes

All reserved special inodes are used for various features (some of them
never been implemented in mainline). This patchset add option for reserving
more special inodes at mkfs time and option to reseze2fs for relocating
first inodes in existing filesystem and reserving them for special usage.

No changes in layout are required because index of first normal inode already
stored in superblock.

[ this is preparation for adding project quota feature ]

Konstantin Khlebnikov (4):
      resize2fs: allocate ext2_resize_t outside of resize_fs
      resize2fs: add option -I for reserving more special inodes
      mke2fs: add options extended option for changing first inode
      e2fsprogs: add test for mke2fs -E first_inode and resize2fs -I
