Once upon a time there was this fine patch set called "improve sync efficiency with sb inode wb list" [1] by Brian Foster, who fixed up the original version by Josef Bacik. I've been running with this since then and it seems to work flawlessly, yet it doesn't seem that this ever got merged..does anybody know why? Waiman Long has been working on something similar with his per-CPU lists, but those patches naturally collide a bit, so I'm wondering what's what. Fwiw the effect of the wb list on systems with many cached inodes is phenomal; it would be a shame if this went unmerged. thanks, Holger [1] http://thread.gmane.org/gmane.linux.file-systems/103940 -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
