When btrfs is running low on metadata space, it needs to force delayed allocation pages to disk. It currently does this with a suboptimal walk of a private list of inodes with delayed allocation, and it would be much better if we used the generic flusher threads. writeback_inodes_sb_if_idle would be ideal, but it waits for the flusher thread to start IO on all the dirty pages in the FS before it returns. This adds variants of writeback_inodes_sb* that allow the caller to control how many pages get sent down. Signed-off-by: Chris Mason <chris.mason@oracle.com> |
