Subject: ext3: Fix writepage credits computation for ordered mode
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=523334ba508a8baaf5fc9f15fbad9ed04f334f48;p=deliverable%2Flinux.git

ext3: Fix writepage credits computation for ordered mode

Original computation forgets to count writes of indirect block themselves
(it only counts with blocks necessary for their allocation) in ordered mode.
