Hi list, Here is v2 for making e2fsprogs support inline data. Now debugfs supports inline data in read-write mode. Meanwhile e2fsck has been improved to support inline data feature. v1->v2: * [mke2fs] automatically set EXT_ATTR feature when INLINE_DATA is set * [debugfs] supports read-write mode In mke2fs, EXT4_FEATURE_INCOMPAT_INLINE_DATA is set to 0x2000 to consist with kernel. When making a new ext4 file system with INLINE_DATA feature, mke2fs will check whether EXT_ATTR is set or not. If it is not set, mke2fs will mark it automatically because INLINE_DATA depends on it. In debugfs, it can support inline data in read-write mode. Now there is two problems that need to be solved. No matter whether the size of data is fit into inline data or not, 'write' command writes the data into disk blocks rather than inode itself. 'mkdir' command will expand dir to a new disk block when inode->i_block has full because Tao found a performance regression when a huge number of dirs are added and removed in EA space. It causes that the code in kernel might be changed. So now 'mkdir' cmd doesn't add a new dir entry in EA space. TODO list: * [mke2fs] initialize ROOT dir with inline data flag * [mke2fs] initialize LOST+FOUND dir with inline data flag * [debugfs] 'write' cmd writes the data into inode itself * [debugfs] 'mkdir' cmd add dir entry into EA space Regards, Zheng libext2fs: add EXT4_FEATURE_INCOMPAT_INLINE_DATA flag mke2fs: make it support inline data feature libext2fs: add inline_data feature mke2fs: add inline_data feature in mke2fs's manpage libext2fs: add ext2fs_find_entry_ext_attr function libext2fs: add EXT4_INLINE_DATA_FL flag for inode libext2fs: add data structures for inline data feature libext2fs: add inline_data file debugfs: make ncheck cmd support inline data debugfs: make chroot and cd cmd support inline data debugfs: make ls cmd support inline data debugfs: make stat cmd support inline data debufs: make blocks cmd support inline data debugfs: make filefrag cmd support inline data debugfs: make link cmd support inline data debugfs: make unlink cmd support inline data debugfs: make mkdir cmd support inline data debugfs: make rmdir cmd support inline data debugfs: make rm and kill_file cmd support inline data debugfs: make pwd cmd support inline data debugfs: make expand_dir cmd support inline data debugfs: make lsdel cmd support inline data debugfs: make undel cmd support inline data debugfs: make dump and cat cmd support inline data debugfs: make rdump cmd support inline data debugfs: make dirsearch cmd support inline data debugfs: make bma cmd support inline data e2fsck: add three problem descriptions in pass1 e2fsck: check incorrect inline data flag e2fsck: make pass1 support inline data libext2fs: add read/write inline data functions e2fsck: check inline data in pass2 debugfs/debugfs.c | 25 ++- debugfs/dump.c | 38 +++- debugfs/filefrag.c | 30 ++- debugfs/htree.c | 6 + debugfs/ls.c | 8 +- debugfs/lsdel.c | 19 +- debugfs/ncheck.c | 8 +- e2fsck/pass1.c | 70 ++++- e2fsck/pass1b.c | 5 +- e2fsck/pass2.c | 50 +++- e2fsck/problem.c | 15 + e2fsck/problem.h | 9 + lib/e2p/feature.c | 2 + lib/ext2fs/Makefile.in | 5 + lib/ext2fs/Makefile.pq | 1 + lib/ext2fs/bmap.c | 16 + lib/ext2fs/dblist_dir.c | 8 +- lib/ext2fs/dirblock.c | 62 ++++ lib/ext2fs/expanddir.c | 8 +- lib/ext2fs/ext2_ext_attr.h | 4 + lib/ext2fs/ext2_fs.h | 9 + lib/ext2fs/ext2fs.h | 69 ++++- lib/ext2fs/ext_attr.c | 26 ++ lib/ext2fs/get_pathname.c | 7 +- lib/ext2fs/inline_data.c | 715 ++++++++++++++++++++++++++++++++++++++++++++ lib/ext2fs/link.c | 9 +- lib/ext2fs/lookup.c | 6 +- lib/ext2fs/mkdir.c | 4 + lib/ext2fs/unlink.c | 9 +- misc/mke2fs.8.in | 3 + misc/mke2fs.c | 10 +- 31 files changed, 1197 insertions(+), 59 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
