Hi Samba gurus,
need your suggestions on where to plant debug code in Linux kernel
to stomp on a bug. Please read on:
> I narrowed down Samba weirdness I observe on 2.4.10 to preempt patch.
> Plain 2.4.10 works fine, 2.4.10+preempt (with latency measurement

2.4.13+preempt exhibits the same bug (even without latency measurement
patch). 2.4.13 plain is ok.
nmbd/smbd are started by inetd on my box, and I usually see creation bug
at first attempt to copy file, susequent copies are usually ok.
I have no idea of where I can start planting preempt_disable() and
preempt_enable() in the 2.4.13 to narrow bug location.
Any suggestions? Samba gurus may be more knowledgeable...
Plase CC me, I'm not on the Samba list. Thanks!
