Message-Id: <1386323897-2354-1-git-send-email-wenqing.lz@taobao.com> Date: Fri, 6 Dec 2013 17:57:47 +0800 From: Zheng Liu <gnehzuil.liu@...il.com> To: linux-ext4@...r.kernel.org Cc: Theodore Ts'o <tytso@....edu>, "Darrick J. Wong" <darrick.wong@...cle.com>, Zheng Liu <wenqing.lz@...bao.com> Subject: [PATCH v3 00/30] e2fsprogs: inline data refinement patch set Hi all, This is the third version of inline data patch set for e2fsprogs. In this version, I made most changes according to Darrick's comments. As always any comment or suggestion are welcome. Ted, patch 01 ~ 08 are taken from Darrick's patchbomb. I don't touch them. Please let me know if I can do something for your review. Darrick, I don't pick up your patch that tries to handle _DIR_NO_SPACE error in ext2fs_link() because after applied that path some tests won't pass. So I prefer to put this problem into TODO list. changelog: v3: * Check inline_data feature in extended attribute API [patch 09] * Define a new interface (ext2fs_dirent_swab_in2/out2) [patch 10] for inline data and use them in ext2fs_inline_data_dir_iterate() [patch 11, 14] * Define a new flag (BLOCK_INLINE_DATA_CHANGED) to reflect that inline data has been changed [patch 17] * Use ext2fs_bmap2() in ext2fs_inline_data_expand() [patch 17] * Return EXT2_ET_INLINE_DATA_NO_BLOCK in ext2fs_bmap2() [patch 17] * Refactor out the code of ext2fs_inline_data_expand() [patch 19] * Remove useless variable 'start' [patch 19] * Typo fixes [patch 21,22] * Turn off inline_data feature in tune2fs [patch 22] * Change type from 'int' to 'unsigned int' for cache_size [patch 29] v2: * Rebase against e2fsprogs/next branch * Based against darrick's extended attribute API * Remove 'libext2fs: add INLINE_DATA into EXT2_LIB_SOFTSUPP_INCOMPAT' patch that has been applied * Refine the interface of inline data. Now no any interface is exported to outside caller. All interfaces are only exported for developers * Refactor ext2fs_inline_data_dir_iterate() so that it can call ext2fs_process_dir_block directly * Fix big-endian problem in handle parent inode in i_block * Remove ext2fs_inode_has_inline_data() interface * Export inode cache creation interface for unit test * Coding style fixes * Bug fixes v1: * Revise the interfaces of liext2fs. * Implement ext2fs_punch_inline_data in lib/ext2fs/punch.c. Now if you want to truncate an inode with inline data, you need to call ext2fs_punch(), and it will handle inline data. * Remove ext2fs_inline_data_dirsearch() function. Now we don't support dirsearch command for an inode with inline data in debugfs. * Ext2fs_mkdir() refinement. Now if we want to create a directory with inline data, we just need to call ext2fs_mkdir(). This function will try to create a new directory with inline data if inline_data feature is enabled. * Fix big-endian bug in some functions. When ext2fs_read_inode() tries to read an inode into memory, it will handle big-endian by itself. Thus, we don't need to handle it manually. * Fix a bug in e2fsck/pass3. When we try to expand a 'lost+found' dir, we don't need to handle inline data because this dir shouldn't have this flag. Regards, - Zheng Darrick J.
