Subject: [fs] ext4: add missing aops
Message-id: 48F36474.4020804@redhat.com
O-Subject: [RHEL5.3 PATCH] ext4: add missing aops
Bugzilla: 466246
RH-Acked-by: Rik van Riel <riel@redhat.com>

This is for
[Bug 466246] Interactive installation fails with ext4dev root partition

Embarrassingly enough, I missed a few aops on the backport -
and missing ->sendfile caused the problem with the installer
(LOOP_CHANGE_FD fails without it, and anaconda uses this)

This was tested an found to resolve the issue.

Thanks,
-Eric
