2020-01-19Cleanup: remove the payload pointers from sqfs_inode_generic_tDavid Oberhollenzer
There are 3 types of extra payload: - Directory index - File block sizes - Symlink target This commit removes the type specific pointers and modifies the code to use the payload area directly. To simplify the file block case and mitigate alignment issues, the type of the extra field is changed to sqfs_u32. For symlink target, the extra field can simply be cast to a character pointer (it had to be cast anyway for most uses). For block sizes, probably the most common usecase, it can be used as is. For directory indices, there is a helper function anyway. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
