X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ea5e1675ac832b42889ac8d254ea8fbfbdfaa8b2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git Ocfs2/move_extents: Validate moving goal after the adjustment. though the goal_to_be_moved will be validated again in following moving, it's still a good idea to validate it after adjustment at the very beginning, instead of validating it before adjustment.
