From a2e7d2df82cafb76f76809ddf6e2caa8afe4f75e Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Mon, 6 Apr 2009 19:01:44 -0700 Subject: nilfs2: cleanup nilfs_clear_inode 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.
