I actually dont see the patch that removed the uprobe->pending_list. I dont see it as part of the 7 that you sent yesterday. Nor does is it part of the series that you sent today. the uprobe_mmap_hash was required because we can do only one insert or remove operation at a time. How are we going to synchronize uprobe_mmap() for two different vmas that belong two different mms but map the same inode? May be I am missing a patch somewhere. -- thanks and regards Srikar -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
