[PATCH 2/3] writeback: Export inode_io_list_del()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Ext4 needs to remove inode from writeback lists after it is out of
visibility of its journalling machinery (which can still dirty the
inode). Export inode_io_list_del() for it.
