Test Case: Sequential Regular-File Read

Test ID: TC035-file-read-sequential

Objective

Verify buffered sequential reads return every byte of a deterministic multi-block regular file.

Fixture

Use images/flat.erofs and source/flat/data.txt. Evidence asserts FLAT_PLAIN, NID, and size 262163.

Procedure

stat -f 'size=%z blocks=%b' "$mnt/data.txt"
dd if="$mnt/data.txt" of=/tmp/tc035.out bs=4096
cmp /tmp/repo22-g1/source/flat/data.txt /tmp/tc035.out
sha256 /tmp/repo22-g1/source/flat/data.txt /tmp/tc035.out

Remove output, unmount, and detach.

Expected Results

• dd reaches exact EOF and the complete output matches the source/hash.
• No short read, data corruption, dmesg error, or cleanup failure occurs.
