Possible bug in fs/read_write.c
Function sys_readdir()

	There is a call the verify_area that does not take in account
	the count parameter. I guess it should read

	error = verify_area(VERIFY_WRITE, dirent, count*sizeof (*dirent));

	instead of

	error = verify_area(VERIFY_WRITE, dirent, sizeof (*dirent));

	Of course, now , count is always 1
