Subject: Btrfs: kill unnecessary arguments in del_ptr
X-Git-Tag: upstream/snapshot3+hdmi~5774^2~113
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0e411ecec60138f22442728f036d38cfea007817;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

Btrfs: kill unnecessary arguments in del_ptr

The argument 'tree_mod_log' is not necessary since all of callers enable it.
