# Test Case: getattr Special Files

**Test ID**: TC056-getattr-special
**Category**: Vnode Operations
**Priority**: Critical

## Objective

Verify compact and extended char, block, and FIFO inodes expose exact types,
device numbers, zero size/allocation, and stable generation.

## Procedure

On fresh mounts of metadata/special-compact.erofs and
metadata/special-extended.erofs:

    ./stat_special char /tmp/repo22-g3/mnt/char-large 2748 344865
    ./stat_special block /tmp/repo22-g3/mnt/block-large 2748 344865
    ./stat_special fifo /tmp/repo22-g3/mnt/fifo
    stat -f 'name=%N type=%HT size=%z blocks=%b gen=%v' \
      /tmp/repo22-g3/mnt/char-large \
      /tmp/repo22-g3/mnt/block-large \
      /tmp/repo22-g3/mnt/fifo

## Expected Results

All type/rdev probes pass; each special inode has size and st_blocks zero and
a nonzero generation. Record both fixture hashes and clean each mount/md.
