[PATCH v4 0/4] btrfs-progs: support for fs-verity fstests

[Boris Burkov <boris@bur.io>]

Adding fstests for fs-verity on btrfs needs some light support from
btrfs-progs. Specifically, it needs additional device corruption
features to test corruption detection, and it needs the RO COMPAT flag.

The first patch defines (u64)-1 as "UNSET_U64"
The second patch adds corrupting arbitrary regions of item data with -I.
The third patch adds corrupting holes and prealloc in extent data.
The fourth patch includes BTRFS_FEATURE_RO_COMPAT_VERITY to ctree.h

--
v4: use ternary and get rid of "bogus_type" to cleanup input handling of
    'corrupt_file_extent'
v3: add patch #defining (u64)-1 in btrfs-corrupt-block
    check item bounds in corruption function
    improve usage message for new corruption use case
    add patch with verity ro compat flag
v2: minor cleanups from rebasing after a year  


Boris Burkov (4):
  btrfs-corrupt-block: define (u64)-1 as UNSET_U64
  btrfs-progs: corrupt generic item data with btrfs-corrupt-block
  btrfs-progs: expand corrupt_file_extent in btrfs-corrupt-block
  btrfs-progs: add VERITY ro compat flag
