In ocfs2_dentry_attach_lock(), if unable to get the dentry lock(), we need to call iput(inode) because a failure here means no d_instantiate(), which means the normally matching iput() will not be called during dput(dentry). This patch fixes the oops that accompanies the following message: (3996,1):dlm_empty_lockres:2708 ERR...

Greetings, Last night I manually unpresented and deleted a LUN (a SAN snapshot) that was presented to one node in a four node RAC environment running OCFS2 v1.4.1-1. The system then rebooted with the following error: Oct 21 16:45:34 ausracdb03 kernel: (27,1):o2hb_write_timeout:166 ERROR: Heartbeat write timeout to device dm-24 after 120000 milliseconds Oct 21 16:45:34 ausracdb03 kernel:

In commit ea455f8ab68338ba69f5d3362b342c115bea8e13, we move the dentry lock put process into ocfs2_wq. This is OK for most case, but as for umount, it lead to at least 2 bugs. See http://oss.oracle.com/bugzilla/show_bug.cgi?id=1133 and http://oss.oracle.com/bugzilla/show_bug.cgi?id=1135. And it happens easily if we have opened a lot of inodes. For 1135, the reason is that during umount will call

Hello, the following series of patches fixes some issues with OCFS2 quotas. The first patch modifies VFS quota locking, the next patch uses the fact to simplify OCFS2 quota locking and solves a few deadlock issues. The third and the fourth patches fix another possible deadlocks in OCFS2 quota code and the last patch is a minor cleanup. Honza

Hi all, So I have finally finished the v1 of reflink for ocfs2. It has some bugs that I am still investigating, but the schema is almost there. So I'd like to send it out first for review. And Tristan and I will continue to work on the stability of the code. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink. For the design doc, please
