Fixes to the BFS filesystem driver
I found a few bugs in the BFS driver. Detailed description of the bugs as well as the steps to reproduce the errors are given in the kernel bugzilla. Please follow these links for more information: http://bugzilla.kernel.org/show_bug.cgi?id=9363 http://bugzilla.kernel.org/show_bug.cgi?id=9364 http://bugzilla.kernel.org/show_bug.cgi?id=9365 http://bugzilla.kernel.org/show_bug.cgi?id=9366 This patch fixes the bugs described above. Besides, the patch introduces coding style changes to make the BFS driver conform to the requirements specified for Linux kernel code. Finally, I made a few cosmetic changes such as removal of trivial debug output. Also, the patch removes the fields `si_lf_ioff' and `si_lf_sblk' of the in-core superblock structure. These fields are initialized but never actually used. If you are wondering why I need BFS, here is the answer: I am using this driver in the context of Linux kernel classes I am teaching in the Moscow State University and in the International Institute of Information Technology in Pune, India.
