  "message": "ext4: add KUnit tests for fs/ext4/dir.c\n\nAdd a KUnit test suite (ext4_dir_test) in fs/ext4/dir-test.c covering\ndirectory entry validation, hash-cookie helpers, directory llseek, and\nboth linear and HTree directory iteration in fs/ext4/dir.c:\n\n- __ext4_check_dir_entry() and ext4_check_all_de() validation across\n  valid blocks (including fake \u0027.\u0027, \u0027..\u0027, and metadata_csum tail\n  entries, as well as encrypted+casefolded extended-hash entries) and\n  corrupt rec_len, alignment, name_len, block-end slack, overrun,\n  out-of-bounds inode numbers, and full-block \u0027.\u0027 entries.\n- is_dx_dir(), get_dtype(), and 32-bit vs 64-bit HTree telldir hash\n  position conversions (hash2pos, pos2maj_hash, pos2min_hash, and\n  ext4_get_htree_eof).\n- ext4_dir_operations open(), llseek() (64-bit and 32-bit HTree EOF\n  bounds vs non-DX s_bitmap_maxbytes/SEEK_END bounds and cookie\n  invalidation), and release().\n- ext4_htree_store_dirent() rbtree ordering across major/minor hashes,\n  64-bit hash collision chaining, and ext4_htree_free_dir_info().\n- Linear ext4_readdir() across multi-block directories with sparse\n  holes, deleted entries, stop/resume, unaligned f_pos revalidation on\n  i_version change, bad checksum and corrupt entry skipping, and\n  ERR_BAD_DX_DIR fallback clearing EXT4_INODE_INDEX.\n- HTree ext4_dx_readdir() across multi-leaf next_hash continuations,\n  mid-collision extra_fname stop/resume, EOF handling, seek reset, and\n  mid-iteration i_version refill.\n\nExport ext4_dir_operations, expose thin KUnit wrappers for static\nhelpers in fs/ext4/dir.c, and add a KUNIT_STATIC_STUB_REDIRECT hook to\next4_htree_fill_tree().\n\nSigned-off-by: Theodore Ts\u0027o \u003ctytso@mit.edu\u003e\n",
