-# Minimalist mconsole exec patch
-#
-# 3.10 version (with bit more synchronous behavior) by fingon at iki dot fi
-# Adaptation to kernel 3.3.8 made by David Fernández (david at dit.upm.es) for
-# Starting point: mconsole-exec-2.6.30.patch for kernel 2.6.30
-# Author of original patch: Paolo Giarrusso, aka Blaisorblade
-# (http://www.user-mode-linux.org/~blaisorblade)
-#
-# Known misfeatures:
-#
-# - If output is too long, blocks (and breaks horribly)
-# (this misfeature from 3.10 patches, when minimalizing the patch;
-# workaround: redirect to a shared filesystem if long output is expected)
-#
-# - Nothing useful is done with stdin

+# Starting point: mconsole-exec-2.6.30.patch for kernel 2.6.30
+# Author of original patch: Paolo Giarrusso, aka Blaisorblade
+# (http://www.user-mode-linux.org/~blaisorblade)
+#
+# Known misfeatures:
+#
+# - If output is too long, blocks (and breaks horribly)
+# (this misfeature from 3.10 patches, when minimalizing the patch;
+# workaround: redirect to a shared filesystem if long output is expected)
+#
+# - Nothing useful is done with stdin
