-	  This causes JFFS2 to read back every page written through the
-	  write-buffer, and check for errors.
+	  Read back data immediately after flash writes and compare it
+	  with the in-memory image that was written. This covers both
+	  write-buffer flushes and direct writes to non-writebuffered
+	  devices.
+
+	  This may catch corruption introduced after node CRCs are
+	  calculated but before/while data is transferred to the flash
+	  controller (e.g. RAM or DMA), where mtd_write() may succeed
+	  while the medium does not match what JFFS2 intended.
+
+	  Without an immediate read-back, a later node CRC failure cannot
+	  tell transport/program-time corruption from post-commit media
+	  damage.
+
+	  If unsure, say 'N'.
