Subject: warning fix: unsigned->signed
From: "Tomasz Kvarsin" <kvarsin@xxxxxxxxx>
While compiling my code with -W, I always get bunch of warrning from
headers, here is fix for them:
__getblk is alawys called with unsigned argument,
but it takes signed, the same story with __bread,__breadahead and so on.
