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
