These two patches are the start of cleaning up the union of
filesystem-specific structures in struct super_block.  The goal is to
remove dependence on filesystem headers in fs.h.  The first patch
abstracts the access to the minix_sb_info structure through the function
minix_sb().  The second patch switches to using kmalloc to allocate the
structure.

Patches are against 2.5.6.
