      ext4: Expand extra_inodes space per the s_{want,min}_extra_isize fields · 6dd4ee7c
      Kalpak Shah authored
      
      
      We need to make sure that existing ext3 filesystems can also avail the
      new fields that have been added to the ext4 inode. We use
      s_want_extra_isize and s_min_extra_isize to decide by how much we should
      expand the inode. If EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE feature is set
      then we expand the inode by max(s_want_extra_isize, s_min_extra_isize ,
      sizeof(ext4_inode) - EXT4_GOOD_OLD_INODE_SIZE) bytes. Actually it is
      still an open question about whether users should be able to set
      s_*_extra_isize smaller than the known fields or not.
      
      This patch also adds the functionality to expand inodes to include the
      newly added fields. We start by trying to expand by s_want_extra_isize
      bytes and if its fails we try to expand by s_min_extra_isize bytes. This
      is done by changing the i_extra_isize if enough space is available in
      the inode and no EAs are present. If EAs are present and there is enough
      space in the inode then the EAs in the inode are shifted to make space.
      If enough space is not available in the inode due to the EAs then 1 or
      more EAs are shifted to the external EA block. In the worst case when
      even the external EA block does not have enough space we inform the user
      that some EA would need to be deleted or s_min_extra_isize would have to
      be reduced.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
