From 847c9db5cb50841589b8ebd3da0769b1b02fb3b2 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 12 Feb 2012 21:00:05 -0500 Subject: [PATCH] ocfs2: deal with wraparounds of i_nlink in ocfs2_rename() unfortunately, nlink_t may be smaller than 32 bits and ->i_nlink on ocfs2 can grow up to 0xffffffff; storing it in nlink_t variable will lose upper bits on such architectures. Needs to be made u32, until we get kernel-side nlink_t uniformly 32bit...
