函数名称：show_vfsstat

函数原型：static int show_vfsstat(struct seq_file *m, struct vfsmount *mnt)

返回类型：int

参数：

类型参数名称
struct seq_file *m
struct vfsmount *mnt
195  p等于private
196  r等于real_mount(mnt)
197  struct path mnt_path = {dentry = root of the mounted tree , mnt = mnt}
198  sb等于 The root of the dentry tree
202  如果show_devname则
203  seq_puts(m, "device ")
204  err等于show_devname(m, dentry)
205  如果err则转到:out
207  否则
208  如果 Name of device e.g. /dev/dsk/hda1 则
209  seq_puts(m, "device ")
210  mangle(m, Name of device e.g. /dev/dsk/hda1 )
211  否则seq_puts(m, "no device")
216  seq_puts(m, " mounted on ")
218  err等于Same as seq_path, but relative to supplied root.
219  如果err则转到:out
221  seq_putc(m, ' ')
224  seq_puts(m, "with fstype ")
225  show_type(m, sb)
228  如果show_stats则
229  seq_putc(m, ' ')
230  err等于show_stats(m, dentry)
233  seq_putc(m, '\n')
234  out :
235  返回:err
