------------------------------------------------------
Subject: nilfs2: cleanup nilfs_clear_inode
From: Ryusuke Konishi <konishi.ryusuke@xxxxxxxxxxxxx>
This will remove the following unnecessary locks and cleanup code in
nilfs_clear_inode():
- unnecessary protection using nilfs_transaction_begin() and
nilfs_transaction_end().
- cleanup code of i_dirty list field which is never chained
when this function is called.
- spinlock used when releasing i_bh field.
