Andrey Smetanin (38):
  ploop: fix accounting ploop_io_images_size
  ploop: fix dio_fsync wait
  ploop: check new size of block device on ioctl(GROW)
  ploop: prevent dangerous ploop-umount
  ploop: prevent disclosure 4 bytes of the stack kernel
  ploop: report holes in pio_direct (v2)
  ploop: rework accounting images_size
  ploop: fix iblk-to-sector calculations
  ploop: fix sync delay for sync requests
  ploop: reverse order of fdatawait and fsync fop
  ploop: skip writes of zeroes to unallocated blocks by default
  ploop: support 4K block-size of host block-device
  ploop: fix a race condition on relocation of blocks
  ploop: fix check_zero optimization v2
  ploop: fix race in ploop_tracker_init()
  ploop: prioritize BAT operations
  ploop: add ioctl to limit size of top delta (v2)
  ploop: bug on bad fiemap (v2)
  ploop: ensure non-empty delta list on running ploop
  ploop: expose open_count to sysfs
  ploop: fix spurious hole complains
  ploop: put top-delta back if merge failed
  ploop: roll back alloc_head on ENOSPC
  ploop: zero blocks on reuse
  ploop: make manual abort transition verbose
  ploop: warning on "disk full" condition
  ploop: add a separate queue for discard bio-s (v2)
  ploop: notify blktrace about bio completions
  ploop: fix busyloop on secondary discard bio
  Series description:
  ploop: define struct ploop_request->state flags to force pre FLUSH
    before write IO and FUA/fsync at I/O complete
  ploop: direct: to support truly FLUSH/FUA of req we need mark first
    bio FLUSH, write all bios and mark last bio as FLUSH/FUA
  ploop: do preflush or postfua according force FUA/flush flags, and
    delay FUA if possible but add force FLUSH to req if so
  ploop: make image fsync at I/O complete if it's required by FUA/fsync
    force flag or by req->req_rw
  ploop: mark reloc reqs to force FUA before write of relocated data
  ploop: mark reloc reqs to force FUA/fsync(kaio) for index update I/O
  ploop: force FUA of nullified blocks for BAT grow
  ploop: added printk of function, line, backtrace before
    ploop_set_error
