Subject: [Bug kprobes/2453] kernel panic when probe elv_dequeue_request
Date: Thu, 16 Mar 2006 00:30:00 -0000 [thread overview]
Message-ID: <20060316003035.5409.qmail@sourceware.org> (raw)
In-Reply-To: <20060313083449.2453.guanglei@cn.ibm.com>
------- Additional Comments From jkenisto at us dot ibm dot com 2006-03-16 00:30 -------
Some questions come to mind:
a. Do we see the BUG only when there's a probepoint on elv_dequeue_request?
b. Is single-stepping the tdnei instruction somehow causing the BUG?
c. Should we be allowing probepoints on tdnei instructions?
d. Is the tdnei instruction really the first instruction after the function
prolog? (This would make a difference if (b) or (c) comes into play.)
