From ad8453ab0a5b98884074302ba3cc37664791e261 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Wed, 25 Aug 2010 13:26:32 +0100 Subject: [PATCH 1/1] ceph: Fix warnings Just scrubbing some warnings so I can see real problem ones in the build noise. For 32bit we need to coax gcc politely into believing we really honestly intend to the casts. Using (u64)(unsigned long) means we cast from a pointer to a type of the right size and then extend it. This stops the warning spew.
