Subject: New ext4 patchset: 2.6.27-rc3-ext4-1 and 2.6.26-ext4-7

I've released a new ext4 patchset against the 2.6.27-rc3 kernel. This
has more bug fixes that have been reported by benchmarkers and early
users of ext4.

As before I've also released updated the patch set vs. the 2.6.26 stock
kernel, for those people who don't want to play with development kernels
but who still want to test out ext4. The 2.6.26-ext4-7 patchset
contains only the stable patches of ext4.

As a git tree:
