yo
<wmealing>
hey fche!
<wmealing>
did you see myquestion about guru mode yesterday
<wmealing>
can i replace an entire function ?
<fche>
the kernel does not expose such functionality to us, so we can't pass it through
<wmealing>
damn
<fche>
a particularly daring soul could try rewriting the pt_regs we do have
<fche>
to jump over things
<wmealing>
that may be.. a little much for me.
<fche>
yeah
<fche>
what's the purpose this time?
<wmealing>
i gotta insert a lock around a structure.
<wmealing>
lock, and unlock.
<fche>
so you deliberately want to put in a blocking construct into a by-design-nonblocking runtime
<fche>
YOU ARE A BAD MAN
<wmealing>
i know this
<wmealing>
you know this.
<wmealing>
hell is coming with me.
<wmealing>
tldr; attempting to fix a race condition.
<fche>
in the kernel?
<wmealing>
aye
