[PATCH 00/11] verify pattern interval

This patch series adds the verify_pattern_interval option which
refreshes and restarts the verify_pattern every N bytes. This is
intended to be used when verify_pattern contains the %o format specifier
in order to write each offset with its LBA. Doing this 512 bytes at a
time for a large device is slow, so verify_pattern_interval allows fio
to write this pattern in larger chunks.

Patch 1 makes testing easier by adding a verify=pattern_hdr option.
Patches 2-3 fix two bugs found while testing the new feature.
Patch 4 directs fio to omit an inappropriate error message.
Patches 5-7 improve testing.
Patch 8 implements this new feature.
Patches 9-11 add tests to verify the new feature.

Vincent Fu (11):
  verify: add verify mode for a pattern with header
  verify: fix verify_offset when used with pattern_hdr
  verify: make verify_pattern=%o thread safe
  verify: omit verify type mismatch error message for pattern verify
  t/fiotestcommon: lengthen timeout for longer tests
  ci: for nightly verify tests use all checksum methods
  ci: don't skip verify tests when triggered manually
  verify: add verify_pattern_interval option
  t/verify: test cases for running pattern and pattern_hdr
  t/verify: Windows --output work-around
  t/verify: add tests to exercise verify_pattern_interval
