Hmm...but the current code flushes the page. just do it in "lazy" way. much difference ?
I agree the current code flushes the I-cache for all kinds of file systems (for PTEs with the exec bit on). The error is that it does it after the PTE is written. In addition, I wanted to optimize it to gain a few %. Apparently this idea is not much welcome. I can agree that flushing the I-cache (if the architecture requires it) before setting the PTE eliminates the error.
