So I fired up my ia64 compile to check on some ocfs2 warning fixes, and btrfs ones dropped out. You can have ''em if you want ''em, I don''t know what the btrfs policy is here. Simple stuff, mostly %llu vs u64. You can also pull from: git://oss.oracle.com/git/jlbec/linux-2.6.git btrfs-warnings Joel -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
Just happened to notice a bunch of %llu vs u64 warnings. Here''s a
patch
to cast them all.

[PATCH 2/2] btrfs: Fix a trivial warning using max() of u64 vs ULL.
A small warning popped up on ia64 because inode-map.c was comparing a u64 object id with the ULL FIRST_FREE_OBJECTID. My first thought was that all the OBJECTID constants should contain the u64 cast because btrfs code deals entirely in u64s. But then I saw how large that was, and figured I''d just fix the max() call.
