+.feature org.zfsonlinux longname no extensible_dataset
+This feature allows creating files and directories with name up to 1023 bytes
+in length.
+A new dataset property
+.Sy longname
+is also introduced to toggle longname support for each dataset individually.
+This property can be disabled even if it contains longname files.
+In such case, new file cannot be created with longname but existing longname
