[RFC/PATCH v2 0/5] readahead: daemon mode

[Bartosz Golaszewski]

While working on an embedded system running several big services, X-org,
fluxbox, Qt5 etc. where the boot-time was awful, it turned out that the
readahead implementation from systemd (the one that was nuked in 2014)
improves the time needed to start all the programs by a few seconds.

This series introduces a small (LOC < 500) readahead daemon implementation
based on fanotify and readahead syscalls.
