Hi Avantika,
I ran some tests with the uninit_groups feature enabled and got error messages
when running e2fsck on my ext4 partition. e2fsck complains of an invalid
unused inodes count in some group descriptors.
These errors occur when checking groups which have only
Also add generic_find_next_le_bit
This gets used by the ext4 multi block allocator patches.

Aneesh,
The subject is a bit confusing, I presume you mean sparse warnings
yes. I will send an updated patch. The group descriptor bg_flags - le16
conversion
should actually go with the uninitialized block group patch.

Looks like it's a straight forward on Little Endian Architectures.
I see something for powerpc, what about other architectures?

Hi all,
I was looking at the patch queue and see patches with different formats.
If we can standardize on what rest of the linux kernel follows it would
be nice.
First line should be
subsystem_name: A single line description of the patch.
This appear in the subject line of the mail that
Convert s_blocks_count_hi and s_blocks_count to le32_t
This helps in finding BUGs due to direct partial access of
these split 64 bit values
Also fix direct partial access in ext4 code
