The other fixes (all in drivers) are mostly for allocation length fixes, error leg unwinding, suspend races and a missing retry. The patch is available here: git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes The short changelog is: Arnd Bergmann (1): scsi: mylex: Fix sysfs buffer lengths Li Nan (1): scsi: sd: Unregister device if device_add_disk() failed in sd_probe() Peter Wang (2): scsi: ufs: core: Fix MCQ mode dev command timeout scsi: ufs: core: WLUN suspend dev/link state error recovery Yihang Li (1): scsi: libsas: Align SMP request allocation to ARCH_DMA_MINALIGN and the diffstat: drivers/scsi/libsas/sas_expander.c | 2 +- drivers/scsi/myrb.c | 20 ++++++++++---------- drivers/scsi/myrs.c | 24 ++++++++++++------------ drivers/scsi/sd.c | 2 +- drivers/ufs/core/ufshcd.c | 9 +++++++-- 5 files changed, 31 insertions(+), 26 deletions(-) With full diff below.
