From 9bc57e2d19db4da81c1150120658cc3658a99ed4 Mon Sep 17 00:00:00 2001 From: Ralph Campbell Date: Fri, 11 Aug 2006 14:58:09 -0700 Subject: IB/uverbs: Pass userspace data to modify_srq and modify_qp methods Pass a struct ib_udata to the low-level driver's ->modify_srq() and ->modify_qp() methods, so that it can get to the device-specific data passed in by the userspace driver.

This, in turn, will cause a device reset, which we hope will recover from the catastrophic condition. Since this might interefere with debugging the root cause, add a module option to suppress this behaviour. Signed-off-by: Jack Morgenstein Signed-off-by: Michael S.
