Merge tag 'for-linus-20180920' of git://git.kernel.dk/linux-block
Jens writes:
"Storage fixes for 4.19-rc5
- Fix for leaking kernel pointer in floppy ioctl (Andy Whitcroft)
- NVMe pull request from Christoph, and a single ANA log page fix
(Hannes)
- Regression fix for libata qd32 support, where we trigger an illegal
active command transition. This fixes a CD-ROM detection issue that
was reported, but could also trigger premature completion of the
internal tag (me)"
* tag 'for-linus-20180920' of git://git.kernel.dk/linux-block:
floppy: Do not copy a kernel pointer to user memory in FDGETPRM ioctl
libata: mask swap internal and hardware tag
nvme: count all ANA groups for ANA Log page
