函数原型：static int pseudo_fs_fill_super(struct super_block *s, struct fs_context *fc)

返回类型：int

参数：

类型参数名称
struct super_block *s
struct fs_context *fc
248  ctx等于fs_private
251  s_maxbytes等于Page cache limit. The filesystems should put that into their s_maxbytes limits, otherwise bad things can happen in VM.
252  s_blocksize等于PAGE_SIZE
253  s_blocksize_bits等于PAGE_SHIFT determines the page size
254  s_magic等于magic
255  s_op等于如果ops否则simple_super_operations
256  s_xattr等于xattr
257  s_time_gran等于1
258  root等于取新的索引节点
259  如果非root则返回:负ENOMEM
267  Stat data, not accessed from path walking 等于1
268  i_mode等于S_IFDIR按位或S_IRUSR按位或S_IWUSR
269  i_atime等于i_mtime等于i_ctime等于rrent_time - Return FS time*@inode: inode.* Return the current time truncated to the time granularity supported by* the fs.* Note that inode and inode->sb cannot be NULL.* Otherwise, the function warns and returns time without truncation.
270  s_root等于d_make_root(root)
271  如果非s_root则返回:负ENOMEM
273  s_d_op等于dops
274  返回:0
