@sudip, I used the same config file before this tag and no problem. The whole config file maybe too much, can you tell me which part to post? I will post the file later. @valdis, I am doing that on a laptop. I try to get back the file by deleting unpack.h and checkout, but the same content remains. And `git status` or `git log` doesn't show any changes of file "unpack.h" . One suspicious action is that, I ever moved the whole directory of linux-master from ext4 to a ntfs driver and compiled it by mounting it back. So, there is some way to get the right content back? _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
