ceph: lock mutex in ceph_mds_check_access()
a61c6ae 
MDS session OPEN handling replaces mdsc->s_cap_auths under
mdsc->mutex, freeing the previous array and its strings.

ceph_mds_check_access() traverses this array without holding the
mutex.  A concurrent session reopen can therefore free the array while
it is being inspected, resulting in a use-after-free like this:

blk-mq-dma: fix kernel-doc for integrity DMA iterators
e01b013 
blk_rq_integrity_dma_map_iter_next() documents a @State parameter it
has never had.  It takes (req, dma_dev, iter), as declared in
include/linux/blk-integrity.h, so scripts/kernel-doc reports an "Excess
function parameter 'state' description" warning at
block/blk-mq-dma.c:379.

The wrapped summary lines of both integrity helpers also indent with
tabs directly after "* ", which checkpatch flags as:

  block/blk-mq-dma.c:320: WARNING: please, no space before tabs
  block/blk-mq-dma.c:361: WARNING: please, no space before tabs

Drop the stale parameter description and use spaces for the alignment;
the rendered output is unchanged.  No functional change.

Both issues were found by running scripts/kernel-doc and
scripts/checkpatch.pl over block/, and verified against the prototype
in include/linux/blk-integrity.h.

blk-mq-dma: fix typo in DMA iterator kernel-doc
d022d70 
blk_rq_dma_map_iter_start() and blk_rq_dma_map_iter_next() both
document their return value as "%true ft it did map a segment", where
"ft" should read "if".  The two integrity variants further down spell
it correctly.

No functional change.
