ocfs2: deal with wraparounds of i_nlink in ocfs2_rename() (847c9db5) · Commits · 戴 / test

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... Signed-off-by:
