Thank you, Linus and Brett, for your answers.

I'm not developing linux kernel, I just wanted to experiment with git. And then I didn't know if this is a normal behaviour of git. I'm using windows xp and msysgit for this. And the file system is NTFS. I'm using dual boot to sporadicly use linux and tried also linux in virtual box. But both isn't really good. Maybe one day I dare to use linux as my primary OS.
