Hi there, do you have eth address? Just want to donate for your work too but I don't have bitcoin lol
有一点不太理解, 如果在`MemorySet`中用Vec来存储`MapArea`的话, sys_munmap的时候只能遍历这个Vec来找到对应的MapArea? 还是说后面的章节有进一步的优化设计呢?
请教一下，EasyFileSystem中的open函数，为什么inode_bitmap和data_bitmap都是重新构造的呢？一个已写入了 easy-fs 镜像的块设备上面不也应该存储着这些bitmap嘛？
vfs中的`Inode::create` 一开始判断是否是directory的时候，应该不需要用&mut DiskNode？这里是否改成 `read_disk_inode` 更合适一些？
@wyfcyx 理解了，非常感谢您的答疑解惑！
有一点疑惑的地方：每次处理trap的时候从call trap_handler一直到__switch函数执行，这中间的调用链是有一些压栈操作的，但是当一个task exit之后，就再也不会__switch回来了，那么这个task对应的调用链里的栈空间就是无法再使用了是么？ 不清楚是我的理解不对，还是目前的设计没有考虑到这一点，谢谢！
