+/* There are several reasons to restrict the linkEA size:
+ *
+ * 1. Under DNE mode, if we do not restrict the linkEA size, and if there
+ * are too many cross-MDTs hard links to the same object, then it will
+ * casue the llog overflow.
+ *
+ * 2. Some backend has limited size for EA. For example, if without large
+ * EA enabled, the ldiskfs will make all EAs to share one (4K) EA block.
+ *
+ * 3. Too many entries in linkEA will seriously affect linkEA performance
+ * because we only support to locate linkEA entry consecutively. */
