Subject: POSIX_FADV_NOREUSE and O_STREAMING behavior in 2.6.7
Date: Thu, 26 Aug 2004 11:39:36 -0600	[thread overview]
Message-ID: <412E2058.60302@rtlogic.com> (raw)

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
