Two core fixes. One simply moves an annotation from put to release to avoid the warning triggering needlessly in alua, but to keep it in case release is ever called from that path (which we don't think will happen). The other reverts a change to the PQ=1 target scanning behaviour that's under intense discussion at the moment. 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: core: Fix the scsi_device_put() might_sleep annotation Martin K. Petersen (1): scsi: Revert "scsi: core: map PQ=1, PDT=other values to SCSI_SCAN_TARGET_PRESENT" And the diffstat: drivers/scsi/scsi.c | 2 -- drivers/scsi/scsi_scan.c | 7 +++---- drivers/scsi/scsi_sysfs.c | 2 ++ 3 files changed, 5 insertions(+), 6 deletions(-) With full diff below.
