         cpufreq core and contained inside cpufreq.c. Other dependent
         drivers should not use it in order to safely avoid lockdep issues.

+What:   sound-slot/service-* module aliases and related clutters in
+        sound/sound_core.c
+When:   August 2010
+Why:    OSS sound_core grabs all legacy minors (0-255) of SOUND_MAJOR
+        (14) and requests modules using custom sound-slot/service-*
+        module aliases.  The only benefit of doing this is allowing
+        use of custom module aliases which might as well be considered
+        a bug at this point.  This preemptive claiming prevents
+        alternative OSS implementations.
+
+        Till the feature is removed, the kernel will be requesting
+        both sound-slot/service-* and the standard char-major-* module
+        aliases and allow turning off the pre-claiming selectively via
+        CONFIG_SOUND_OSS_CORE_PRECLAIM and soundcore.preclaim_oss
+        kernel parameter.
+
+        After the transition phase is complete, both the custom module
+        aliases and switches to disable it will go away.  This removal
+        will also allow making ALSA OSS emulation independent of
+        sound_core.  The dependency will be broken then too.
