From f185ff979f97943c9d4966ed4edc9819c3342c5b Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Fri, 27 Dec 2013 11:01:54 +0900 Subject: [PATCH] f2fs: don't need to get f2fs_lock_op for the inline_data test This patch locates checking the inline_data prior to calling f2fs_lock_op() in truncate_blocks(), since getting the lock is unnecessary.
