Mike ---------------------------------------------------------------- Two stable@ fixes: - DM thinp fix to properly advertise discard support as disabled for thin devices backed by a thin-pool with discard support disabled. - DM crypt fix to prevent the creation of bios that violate the underlying block device's max_segments limits. This fixes a relatively long-standing NCQ SSD corruption issue reported against dm-crypt ever since the dm-crypt cpu parallelization patches were merged back in 4.0. ---------------------------------------------------------------- Mike Snitzer (2): dm thin: disable discard support for thin devices if pool's is disabled dm crypt: constrain crypt device's max_segment_size to PAGE_SIZE drivers/md/dm-crypt.c | 17 +++++++++++++++-- drivers/md/dm-thin.c | 4 ++++ 2 files changed, 19 insertions(+), 2 deletions(-)
