From: Dan Carpenter <[email protected]>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit e7cb08e894a0b876443ef8fdb0706575dc00a5d2 upstream.
We accidentally overwrite the original saved value of "flags" so that we
can't re-enable IRQs at the end of the function. Presumably this
function is mostly called with IRQs disabled or it would be obvious in
testing.
Fixes: aceeffbb59bb ("zfcp: trace full payload of all SAN records
(req,resp,iels)")
