I'd like to invalidate/free the filesystem caches and io buffer cache How can I do this when I can't unmount the filesystem (and w/o reboot) ?
(I run filesystem I/O test that needs to start from fresh cache & buffer state -- as emty as possible, like right after mount/boot).
I tried 'mount -o remount' but it didn't make any difference on the timing. Apparently 'mount -o remount' did not invalidate cases/buffers ? ( The difference between fresh run vs non-fresh run timing is x5 times ).
