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
