The ext4l driver provides more complete ext4 support than the existing ext4 driver, including proper handling of extents, directory hashing, and other ext4 features. Changes include: Sandbox infrastructure: - Fix IRQ macros and buffer_head includes for sandbox builds Core fixes: - Fix path lookup by implementing proper dentry operations - Fix fscrypt_match_name to do actual name comparison Filesystem operations: - Add directory listing (opendir/readdir/closedir) - Add file existence check (exists) - Add file size query (size) - Add file read support (read) - Add UUID query (uuid) - Add filesystem statistics (statfs) New command: - Add fsinfo command to display filesystem statistics Testing: - Add comprehensive unit tests for all operations - Enable fsuuid command for sandbox testing Simon Glass (16): CLAUDE.md: Add note about test-declaration placement buildman: Fix flaky test_kconfig_change test properly linux: buffer_head: Include atomic.h directly sandbox: Convert IRQ macros to static inline functions ext4l: Fix path lookup by implementing dentry operations cmd: Enable fsuuid command for sandbox ext4l: Fix comment formatting test: ext4l: Handle variable console output in tests ext4l: Add open/read/close directory ext4l: Add exists() support ext4l: Add size() support ext4l: Add read() support ext4l: Add uuid() support fs: Add statfs method to the filesystem interface cmd: Add fsinfo command fs: ext4l: Add statfs support CLAUDE.md | 2 + arch/sandbox/include/asm/system.h | 10 +- cmd/Kconfig | 11 + cmd/fs.c | 14 ++ doc/usage/cmd/fsinfo.rst | 53 +++++ doc/usage/index.rst | 1 + fs/ext4l/ext4_uboot.h | 16 +- fs/ext4l/interface.c | 352 ++++++++++++++++++++++++++++ fs/fs_legacy.c | 81 ++++++- include/ext4l.h | 77 ++++++ include/fs_cmd.h | 11 + include/fs_legacy.h | 21 ++ include/linux/buffer_head.h | 5 +- include/linux/fs.h | 1 + test/fs/ext4l.c | 300 +++++++++++++++++++++++- test/py/tests/test_fs/test_ext4l.py | 64 ++++- tools/buildman/func_test.py | 8 +- 17 files changed, 998 insertions(+), 29 deletions(-) create mode 100644 doc/usage/cmd/fsinfo.rst
