名称描述
requeue_inodeFind proper writeback list for the inode depending on its current state and* possibly also change of its state while we were doing writeback. Here we* handle things such as livelock prevention or fairness of writeback among* inodes
writeback_sb_inodesWrite a portion of b_io inodes which belong to @sb.* Return the number of pages and/or inodes written.* NOTE! This is called with wb->list_lock held, and will* unlock and relock that for each inode it ends up doing* IO for.
