Similar to Readahead for write access to ide devices

[Bizhan Gholikhamseh (bgholikh)]

Hi All,
My understanding is the readahead algorithm causes kernel to read more
data ahead of the time from ide device, this will improve the
ide access, however, in our case we find out it is also impacting over
all system performance. Is there similar thing for write access for
Linux 2.6.11?
Thanks,
Biz
