The reason it compiles is because it doesn't have the task_dirty_inc call at all. And looking at it more closely, it looks like task_dirty_inc was never exported to modules. Whoops! I'm not sure what the implications of not calling it are (presumably the VMs space accounting gets out of whack), but it was also missing from the upstream version until 2.6.36, so I'll just drop it from the -backport branches. (I suspect I added it when the account_page_dirtied() call was added in 2.6.36 and noticed it was doing it.) In any case, the ceph-client-standalone.git is fixed up, and you should now be able to use either master-backport or unstable-backport. sage > > Regards, > Jeff.Wu > Transoft.inc > Senior software Engineer > > ÿÿ 2010-10-29ÿÿÿÿ 00:54 +0800ÿÿYonggang Liuÿÿÿÿÿÿ > > Solved.
