Without goto #2:
 

-- still assuming that structs and pointers and refs are sequences...
function vfat_create(sequence dir_p, sequence dentry_p, 
                     integer mode, sequence nd_p)
  sequence sb_p
  sequence inode_p
  sequence bh_p
  sequence de_p
  sequence sinfo
  integer res

  sb_p = dir_p[I_SB]
  inode_p = {}
  bh_p = {}

  lock_kernel()

  res = vfat_add_entry(dir_p, dentry_p[D_NAME], 0, sinfo, bh_p, de_p)
  if res >= 0 then
    inode = fat_build_inode(sb_p, de_p, sinfo[I_POS], res)
    brelse(bh_p)
    if length(inode) != 0 then
       res = 0
       inode_p[I_MTIME] = CURRENT_TIME_SEC
       inode_p[I_ATIME] = CURRENT_TIME_SEC
       inode_p[I_CTIME] = CURRENT_TIME_SEC
       mark_inode_dirty(inode_p)
       inode_p[I_VERSION] += 1
       dir_p[I_VERSION] += 1
       dentry_p[D_TIME] = dentry_p[D_PARENT][D_INODE][I_VERSION]
       d_instatiate(dentry_p, inode_p)
    end if
  end if
 	
  unlock_kernel()

  return res
end function

Nah, actually the goto version is not pleasing to my eyes...
