Changes from v9:

  Document the partition hint mask

  Use bitmap_alloc API

  Fixup bitmap memory leak

  Return invalid value if user requests an invalid write hint

  Added and exported a block device feature flag for indicating generic
  placement hint support

  Added statx write hint max field

  Added BUILD_BUG_ON check for new io_uring SQE fields.

  Added reviews

Kanchan Joshi (2):
  io_uring: enable per-io hinting capability
  nvme: enable FDP support

Keith Busch (7):
  block: use generic u16 for write hints
  block: introduce max_write_hints queue limit
  statx: add write hint information
  block: allow ability to limit partition write hints
  block, fs: add write hint to kiocb
  block: export placement hint feature
  scsi: set permanent stream count in block limits
