A single bug fix for hpsa. The user visible consequences aren't clear, but the ioaccel2 raid acceleration may misfire on the malformed request assuming the payload is big enough to require chaining (more than 31 sg entries). The patch is available here: git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes The short changelog is: Don Brace (1): scsi: hpsa: correct ioaccel2 chaining And the diffstat: drivers/scsi/hpsa.c | 7 ++++++- drivers/scsi/hpsa_cmd.h | 1 + 2 files changed, 7 insertions(+), 1 deletion(-) With full diff below.
