POSIX_FADV_NOREUSE and O_STREAMING behavior in 2.6.7

[David Rolenc]

I am trying to get O_STREAMING (Robert Love patch for 2.4) behavior in 
2.6 and just a glance at fadvise.c suggests that POSIX_FADV_NOREUSE is 
not implemented any differently than POSIX_FADV_WILLNEED. Am I missing 
something?  I want to read data from disk with readahead and drop the 
data from the page cache as soon as I am done with it. Do I have to call 
fadvise with POSIX_FADV_DONTNEED after every read?

Thanks,

David Rolenc
