Struct ExtentVerifyCtx 

pub struct ExtentVerifyCtx<'a> {
    pub ino: u32,
    pub generation: u32,
    pub csum: &'a Checksummer,
}

Context for verifying extent-block tail checksums during a tree walk.

Pass Some(&ctx) to lookup_verified / map_logical_verified / collect_all_verified when reading a real on-disk extent tree under a metadata_csum filesystem. Each off-inode block’s ext4_extent_tail.et_checksum is verified against crc32c(seed, ino_le, gen_le, block[..len-4]).

Pass None to skip verification (tests, callers without a Filesystem).

Fields

ino: u32

Inode number that owns this extent tree.

generation: u32

Inode generation field (salts the per-inode CRC).

csum: &'a Checksummer

Mount-wide checksummer (skipped when csum.enabled == false).
