[PATCH 0/2] btrfs: add error injection support for checksum verification

This patchset adds fault injection support for btrfs_data_csum_ok,
enabling controlled simulation of checksum mismatches to test btrfs
silent data corruption detection and reporting paths.

The first patch extends the error injection framework with a new type,
EI_ETYPE_FALSE, which allows bool-returning functions to be overridden
with a false return value directly.

The second patch marks btrfs_data_csum_ok with ALLOW_ERROR_INJECTION
using this new type.

  error-injection: Introduce EI_ETYPE_FALSE for fail_function
  btrfs: Allow error injection on btrfs_data_csum_ok
