3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ben Hutchings <ben@decadent.org.uk>
commit 2ee3e26c673e75c05ef8b914f54fadee3d7b9c88 upstream.
Commit 39c60a0948cc '[SCSI] sd: fix array cache flushing bug causing performance problems' added temp as a pointer to "temporary " and used sizeof(temp) - 1 as its length. But sizeof(temp) is the size of the pointer, not the size of the string constant. Change temp to a static array so that sizeof() does what was intended.
