Subject: [PATCH 1/4] mvsas: bug fix, null pointer may be used
Null pointer exception when mvi_dev is null.
A little more explanation might be helpful. It looks to me that you get
this issue when you have in-flight I/O to a device we've been notified
has gone (because you NULL out lldd_dev in the removal notification
routine).
In which case, don't we have other races where this can happen, like in
mvs_I_T_nexus_reset()?
Agreed...
