[rrd-developers] rrdtool 1.3 cairo switch is done

[Tobias Oetiker]

Dylan,

Don't use O_DIRECT ! O_DIRECT is for people who do their own
caching ... database folks ... we don't ... we just tell the kernel
WHAT it should cache and what it should not cache ...

not sure what bernhards intention was with O_DIRECT.

cheers
