PROBLEM:  (MGO27465A) (PATCH ID: OSF445-055)
********

This patch fixes a problem when the type of SCSI device dynamically changes,
which can result in a kernel memory fault or memory corruption panic.  The
sense inquiry buffer size is allocated too small.


A typical stack trace:

Panic "closef: f_count not 1" due to corruption of 'file' structure
