Subject: [PATCH] f2fs: remove unmatched zero_user_segment when convert inline dentry
Date:   Tue, 3 Apr 2018 19:42:41 +0800

Precedence: bulk

Since the layout of regular dentry block is different from inline dentry
block, zero_user_segment starting from MAX_INLINE_DATA(dir) is not
correct for regular dentry block, besides, bitmap is already copied and
used, so there is no necessary to zero page at all, so just remove the
zero_user_segment is OK.
