    Hi,
    	I am implementing a new file system, in Linux. I have
    borrowed lot of code from Minix for this purpose. I had a
    problem while implementing the function for file_write. I had
    to modify this function a lot for supporting fragments. I
    tried to use all these functions ( memcpy_tofs, memcpy_fromfs,
    memcpy, bcopy, memmove) to copy the contents of the last
    block into one or fragments. When I used memcpy_tofs or
    memcpy_fromfs, I got segmentation faults. And when I used
    the other functions, it only used to copy the first fragment
    properly and not the remaining ones. Could anyone please help
    me in this regard.
Thank you Vamsi
