From: Chen Gang
Date: Wed Oct 30 2013 - 22:53:52 EST

Need signed cast for it, the original author assume the type of 'block'
is long, so just cast to long. The related warnings (with allmodconfig):

fs/befs/linuxvfs.c:136:2: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits]
