That's not an irrational position. File system buffers are *not* dedicated memory for file system caching; they're being used for that because no one has a better use for them at that moment. If an inability to flush them to disk meant that they suddenly became pinned memory, a large copy operation to a yanked USB drive could result in the system having no more allocatable memory. I guess in theory that they could swap them, but swapping out a file system buffer in hopes that sometime in the future it could be properly written doesn't seem very architecturally sound to me. -- -- Christophe Pettus x...@thebuild.com
