Updated ext4 patches for 2.6.18-rc6

[Mingming Cao]

Hello,

Just give you all an update about the latest ext4 patches before I leave
for vacation: The latest ext4 patches (clone ext4 + 48bit ext4) is
against 2.6.18-rc6, as usual, could be found at:

http://ext2.sourceforge.net/ext4/patches/latest/

Haven't done series testing yet, but fsx test runs fine a few hours on
ext4dev filesystem mounted with extents:)

change log since last release (2.6.18-rc4)

rebase ext4/jbd2 clone patches to 2.6.18-rc6 (Mingming Cao<cmm@us.ibm.com>)
rename ext3dev to ext4dev (Randy  Dunlap <rdunlap@xenotime.net>, Mingming Cao <cmm@us.ibm.com)
register-ext4dev.patch
+register-jbd2.patch

*comment fixs in extent patch (Randy  Dunlap <rdunlap@xenotime.net>)
+extents_comment_fix.patch

*change some micro and inline functions to c fuctions(Avantika Mathur<mathur@us.ibm.com)
+64bitmetadata_inline_funcs_fix.patch

*change ext4/jbd2 block type from sector_t to unsigned long long. (Mingming Cao<cmm@us.ibm.com>). remove sector_fmt.patch
+ext4_blk_type_from_sector_t_to_ulonglong.patch
+ext4_remove_sector_t_bits_check.patch
+jbd2_blks_type_from_sector_t_to_ull.patch
-sector_fmt.patch

Andrew, you could pull all the patches(in quilt style) from here(a
series of patches)
http://ext2.sourceforge.net/ext4/patches/latest/broken-out/

Shaggy has nicely offered to maintain and forward all these patches from
here while I am out, thanks, Shaggy:)

Thanks,
Mingming

Hi Mingming,

I found a trivial bug in Mingming's ext4 patch titled
"ext4-extents-48bit.patch".

There happens a type conflicting:

+int ext4_ext_get_blocks(handle_t *handle, struct inode *inode, ext4_fsblk_t iblock,

You should fix extern declaration for ext4_ext_get_blocks.


Cheers, sho

hi,

there are 2 more patches:

* ext4_remove_relative_block_numbers:

  use 48bit absolute block numbers instead of mixed relative/absolute block
  numbers. This is simpler and seems to fix issues with large file systems.
   
* ext4_allow_larger_descriptor_size:

  allow larger block group descriptors: this patch will allow to add new
  features that need more space in the block descriptor.

here is the complete patch set:

http://www.bullopensource.org/ext4/20060908/ext4-linux-2.6.18-rc6.tar.gz

there's also a patch set for the latest e2fsprogs that is in sync with the
kernel patches:

http://www.bullopensource.org/ext4/20060908/ext4-e2fsprogs-1.39.tar.gz

cheers,

Hmm, I'm a bit confused.  If we are adding larger block group descriptors,
why wouldn't we put 32-bit "high" block numbers into the larger descriptor
space?  That could be part of the INCOMPAT_64BIT support.

Cheers, Andreas
