From da17eece035d72cb50d48529744a490784f29d2f Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Mon, 9 Feb 2015 10:34:38 -0800 Subject: f2fs: call set_buffer_new for get_block This patch fixes wrong handling of buffer_new flag in get_block. If f2fs allocates new blocks and mapped buffer_head, it needs to set buffer_new for the bh_result.
