-  Reference implementation of a few boot readahead related
-  interfaces. These interfaces are trivial to implement. To simplify
-  porting we provide this reference implementation.  Applications are
-  welcome to reimplement the algorithms described here if they do not
-  want to include these two source files.
-
-  You may compile this with -DDISABLE_SYSTEMD to disable systemd
-  support. This makes all calls NOPs.
-
-  Since this is drop-in code we don't want any of our symbols to be
-  exported in any case. Hence we declare hidden visibility for all of
-  them.
-
-  You may find an up-to-date version of these source files online:
-
-  http://cgit.freedesktop.org/systemd/plain/src/sd-readahead.h
-  http://cgit.freedesktop.org/systemd/plain/src/sd-readahead.c
-
-  This should compile on non-Linux systems, too, but all functions
-  will become NOPs.
-
-  See sd-readahead(7) for more information.
