X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=93f9052643409c13b3b5f76833865087351f55b8;p=deliverable%2Flinux.git

ext4: set bg_itable_unused when resizing

Set bg_itable_unused for file systems that have uninit_bg enabled.
This will speed up the first e2fsck run after the file system is
resized.
