The problem that arose was that the directory had grown to 176mb, and in a tight memory cgroup (say, 512mb, or some such), this could cause significant memory thrashing, or the actual OOM killing of the task in said tight memory cgroup when it tried to read the entire directory via readdir(). > If that's the case, this should probably be proposed as a VFS level > option, and see how it's received there... It's not really a VFS level thing, since the goal is to stop the directory size itself from growing beyond a size limit (say, 1mb). - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
