[PATCH] ext4: do less extent validations

[Thiemo Nagel <thiemo.nagel@ph.tum.de>]

[-- Attachment #1: Type: text/plain, Size: 268 bytes --]


Based on 2.6.29-rc7 with Aneesh Kumar's patches:
ext4: Validate extent details only when read from the disk
ext4: Add checks to validate extent entries

Sets need_to_validate=0 inside instead of outside the loop.
