Two small fixes, the drivers one in ufs simply delays running a work
queue and the generic one in zoned storage switches to a more correct
API that tries the standard buddy allocator first (for small
allocations); this fixes an problem with small allocations seen under
memory pressure.
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes
The short changelog is:
Bart Van Assche (1):
scsi: ufs: core: Start the RTC update work later
Johannes Thumshirn (1):
scsi: sd_zbc: Use kvzalloc() to allocate REPORT ZONES buffer
