我试图挂载以前只读挂载的文件系统read-writeable：
mount -o remount,rw /mountpoint
不幸的是它没有工作：
mount: /mountpoint not mounted already, or bad option
dmesg 报告：
[2570543.520449] EXT4-fs (dm-0): Couldn't remount RDWR because of unprocessed orphan inode list. Please umount/remount instead
Aumount也不起作用：
umount /mountpoint
umount: /mountpoint: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
不幸的是没有lsof的fuser不显示位于挂载点下的任何进程访问的东西。
那么 - 我怎样才能清理这个未处理的孤立列表，以便能够在不重新启动计算机的情况下再次挂载文件系统？
