File system using stacked.

2003-10-29  Aditya Kashyap  <[e-mail]>

	* os.h:     Changed the file descriptor in the __fh_t structure to
	            a struct file * to be compatible with the return
	            values of filp_open.

	* mutex.h:  Added __KERNEL__.  Defined semaphore replacements for
	            the mutex calls.  Implementation does not use pthreads
	            anymore, instead makes calls to sema_init,
	            down_interruptible and up.  Changed __db_mutex_* calls
	            to point to __db_tas_*, which in turn calls the
	            kernel semaphore implementations.  Also changed struct
	            __mutex_t to change type of tas to struct semaphore.
