[PATCH v1 00/30] Ext4 snapshots

[amir73il@users.sourceforge.net]

Hi All,

I am resending the snapshots patch series as per Lukas's request.
This time, the snapshot*.c files have not been omitted, as in
the previous posting.

The series is still based on ext4 dev branch sometime in the preparation
for 3.0 merge window. It was not yet rebased on 3.0-rc1, so punch holes
changes have not been addressed yet.

As always, I advocate online review of the patches at:
https://github.com/amir73il/ext4-snapshots/commits/for-ext4-v1
but if you insist on doing it the old way, I won't complain.

Thanks,
Amir.
