#     Merge tag 'for-linus-20181205' of git://git.kernel.dk/linux-block
#     
#     Pull block fixes from Jens Axboe:
#      "A bit earlier in the week as usual, but there's a fix here that should
#       go in sooner rather than later.
#     
#       Under a combination of circumstance, the direct issue path in blk-mq
#       could corrupt data. This wasn't easy to hit, but the ones that are
#       affected by it, seem to hit it pretty easily. Full explanation in the
#       patch. None of the regular filesystem and storage testing has
#       triggered it, even though it's been around since 4.19-rc1.
#     
#       Outside of that, whitelist trim tweak for certain Samsung devices for
#       libata"
