There's nothing there. Forgot to push?

Oops, argh.   Pushed.  Could you retry the pull?

Hi Ted,

Any ideas why the patch fixing accounting of i_blocks in
ext4_free_blocks() didn't come to this set of changes?

The problem was that ext4_free_blocks() calls dquot_free_block() that,
in turn, calls inode_sub_bytes() decrementing i_blocks. This works
fine in most cases but the one: ext4_ext_map_blocks() might call
ext4_free_blocks (if ext4_ext_insert_extent failed) when allocated
blocks were only reserved, i.e. not accounted in i_blocks yet.

I recently re-run a simple test reproducing the problem and found out
that Linus' 3.0.0-rc6 is still affected by this problem. Does it make
sense to resend that patch to you?

Thanks,
Maxim
