Glauber, The patch entitled sl[au]b: Allocate objects from memcg cache changes include/linux/slub_def.h | 15 ++++++++++----- which triggers this warning: drivers/video/riva/fbdev.c:281:9: sparse: preprocessor token MAX_LEVEL redefined It's the MAX_LEVEL that is defined in include/linux/idr.h. MAX_LEVEL is obviously too generic. Better adding some prefix to it? Thanks, Fengguang -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
