	132	+ * DOC: Extensibility
	133	+ *
	134	+ * Originally, we had planned to allow backward and forward compatible
	135	+ * changes by just adding fields at the end of the structure that are
	136	+ * then not reported on older kernels on read(), and not written to by
	137	+ * older kernels on write(), with the kernel reporting the size it did
	138	+ * accept as the result.
	139	+ *
	140	+ * This would have allowed userspace to detect on read() and write()
	141	+ * which kernel structure version it was dealing with, and if was just
	142	+ * recompiled it would have gotten the new fields, but obviously not
	143	+ * accessed them, but things should've continued to work.
	144	+ *
	145	+ * Unfortunately, while actually exercising this mechanism to add the
	146	+ * hard block reasons field, we found that userspace (notably systemd)
	147	+ * did all kinds of fun things not in line with this scheme:
	148	+ *
	149	+ * 1. treat the (expected) short writes as an error;
	150	+ * 2. ask to read sizeof(struct rfkill_event) but then compare the
	151	+ * actual return value to RFKILL_EVENT_SIZE_V1 and treat any
	152	+ * mismatch as an error.
	153	+ *
	154	+ * As a consequence, just recompiling with a new struct version caused
	155	+ * things to no longer work correctly on old and new kernels.
	156	+ *
	157	+ * Hence, we've rolled back &struct rfkill_event to the original version
	158	+ * and added &struct rfkill_event_ext. This effectively reverts to the
	159	+ * old behaviour for all userspace, unless it explicitly opts in to the
	160	+ * rules outlined here by using the new &struct rfkill_event_ext.
	161	+ *
	162	+ * Userspace using &struct rfkill_event_ext must adhere to the following
	163	+ * rules
111	164	*
112		− * One exception is the kernel -- we already have two event sizes in
113		− * that we've made the 'hard' member optional since our only option
114		− * is to ignore it anyway.
	165	+ * 1. accept short writes, optionally using them to detect that it's
	166	+ * running on an older kernel;
	167	+ * 2. accept short reads, knowing that this means it's running on an
	168	+ * older kernel;
	169	+ * 3. treat reads that are as long as requested as acceptable, not
	170	+ * checking against RFKILL_EVENT_SIZE_V1 or such.
