[sheepdog] [PATCH v5 0/5] add support to non-aglined read/write/create

[Liu Yuan]

v5:
 - simply drop O_DIRECT for read/write/create

v4:
 - do_aligned_write before journaling to avoid double journaling

v3:
 - only read first and last sector for write
 - inline flags_direct
 - use & algo for aligned_sector
 - remove constraint for sheepfs
 - refine test

Liu Yuan (5):
  util: add a helper round_down
  plain store: add support to non-aglined read/write/create
  collie: don't round_up vdi size & read/write
  tests: add a tests/063 to test unaligned read/write/create
  sheepfs: remove the align constraint
