Hello,
I mapped a file to the memory, then copy n chars to this memory.
This should invoke ufs_putpage and the third arg 'len' should be n. However I
found the len is not n but 0. I don't know why the len is 0.
If the code is like below:
char* src;
char buff[] = "Hello";
...
src=mmap(fd, size, ...);
for(i=0; i<sizeof(buff); i++)
src[i] = buff[i];
when the ufs_putpage is called?
