From 3c6c2bebef79999b1827041696dc1881e637e3af Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Tue, 17 Mar 2015 17:16:35 -0700 Subject: f2fs: avoid punch_hole overhead when releasing volatile data This patch is to avoid some punch_hole overhead when releasing volatile data. If volatile data was not written yet, we just can make the first page as zero.
