Hi all,

this series adds more tests for the btrfs read-repair code that exercise
the raid1c3 profile and adds helpers to avoid duplicating too much code
for read repair testing

Changes since v2:
  - use the -b option to btrfs-map-logical-blocks for the $seqres.full
    output
  - don't use _btrfs_no_v1_cache_opt for the new tests
  - add a new test to test interleaved sector corruption repair for
    direct I/O.

Changes since v1:
  - add common helpers for read repair
  - increase the offsets so thay they should be fine with 64k block size
    (although I don't have a system to actually verify that)

Verified on pagesize=sectorsize=64K.

For the whole series.
