profiles: added SAP profile
...
Also added support for the sysctl tunings taken from the
environment and conditional tunings (i.e. not to change
the sysctl settings if the current value is greater than
the new value).
To use the environment variable SEM:
kernel.sem = $SEM
To set the kernel.shmall only if the current value is less
than the 1000000:
kernel.shmall = >$1000000
Both can be combined, e.g.:
kernel.shmall = >$SHMALL

functions: silence errors when remounting nobarriers
...
Some filesystems that are mounted multiple times cannot
be remounted with nobarriers. The error may confuse
users, thus it is better to silence it.

tuned: restart ktune 10 seconds after last SIGUSR2 was received
...
When multiple devices are added into the system, udev restarted ktune
daemon for each new device. This can cause races within ktune. This
mechanism allows triggering just one ktune restart when multiple
devices are inserted.
