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
