Subjectconvert reiserfs to ->evict_inode()
Hello,

commit 845a2cc0507055278e0fa722ed0f8c791b7401dd introduced:

@@ -77,9 +79,14 @@ void reiserfs_delete_inode(struct inode *inode)

+ end_writeback(inode); /* note this must go after the journal_end to prevent deadlock */
+ dquot_drop(inode);
inode->i_blocks = 0;
reiserfs_write_unlock_once(inode->i_sb, depth);
+
+no_delete:
+ end_writeback(inode);
+ dquot_drop(inode);
}
