From: Guo Zhi <redacted> [ Upstream commit d4996c6eac4c81b8872043e9391563f67f13e406 ] Pointers should be printed with %p or %px rather than cast to 'unsigned long' and printed with %lx. Change %lx to %p to print the hashed pointer. Link: https://lore.kernel.org/r/20210929122538.1158235-1-qtxuning1999@sjtu.edu.cn (local) Signed-off-by: Guo Zhi <redacted> Signed-off-by: Martin K.
