Is there any way somebody could please place my name 'Atri Sharma' for the Btree locking contention in the wiki? Done. We're using templates for the project descriptions, and clicking 'edit' leads to editing the template itself, so one has to edit the containing section (or the whole page) instead. david -- To unsubscribe from this list: send the line unsubscribe linux-btrfs in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I don't know what happened to the edit, but I'm sure I moved the 'lock contention' under 'claimed projects' with your name added. Now it's there. david -- To unsubscribe from this list: send the line unsubscribe linux-btrfs in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I am really interested in Btree lock contention project, but it seems to be marked that it has already been done in v3.1 Is the project still open? Can I work on it? Go for it, we still have plenty of lock contention, it's just in 3.1 we switched to a read/write lock which helped a bunch. Still if you have all writers you are going to hit quite a bit of lock contention, especially on the root nodes. If you have ideas go for it.

Re: BTree lock contention
Thanks. I shall mark it as in progress then. For writer's contention, I was thinking of decreasing the lock granularity. I have not really thought about it deeply yet, but my initial plans are to identify areas where we can distribute the locks, and maybe use techniques such as combining trees.
