The most up to date code is found in: git://git.kernel.org/pub/scm/linux/kernel/git/djbw/async_tx.git raid6 It is based on the 2.6.29 kernel plus the patches that were merged for drivers/md/ during the 2.6.30 merge window. There is currently no plan to provide updated patches for kernel versions prior to 2.6.29. > 1) If these are currect one Iam looking, then I have a few more doubts while > traversing the code, It has async calls like async_pq, async_r6_dd_recov, ... > From where these functions are invoked > how the link happens between these async calls and the md-raid driver. > > Can anybody help in solving this problem, it is very useful for my work. > Thanks in advance for your support. Please try the latest code in the raid6 branch, it has been updated according to review comments and includes the changes to drivers/md/raid5.c to invoke asynchronous raid6 operation. Note that this branch of the tree will periodically rebase as review feedback is incorporated into the patches. I understand this makes the tree difficult to track with git. My recommendation is to add it as a remote branch and use git fetch and git reset to stay up to date: git remote add async_tx git://git.kernel.org/pub/scm/linux/kernel/git/djbw/async_tx.git git fetch async_tx git checkout -b test-raid6 async_tx/raid6 ...then to update (assuming you are still on the test-raid6 branch): git fetch async_tx git reset async_tx/raid6 Regards, Dan -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
