Subject: f2fs: Revert "f2fs: truncate blocks in batch in __complete_revoke_list()"
From: Jaegeuk Kim <jaegeuk@xxxxxxxxxx>
commit c7dbc06688292db34c1bb9c715e29ac4935af994 upstream.
We should not truncate replaced blocks, and were supposed to truncate the first
part as well.
This reverts commit 78a99fe6254cad4be310cd84af39f6c46b668c72.
