Hi Varada, Have you rebased the pull request to master already?

Benjamin; Loic Dachary Cc: ceph-devel Subject: RE: loadable objectstore Hi Sage/ Matt, I have submitted the pull request based on wip-plugin branch for the object store factory implementation at https://github.com/ceph/ceph/pull/5884 . Haven't rebased to the master yet. Working on rebase and including new store in the factory implementation. Please have a look and let me know your comments. Will submit a rebased PR soon with new store integration.

Benjamin Subject: RE: loadable objectstore Hi, Made some more changes to resolve lttng problems at https://github.com/varadakari/ceph/commits/wip-plugin. But couldn’t by pass the issues. Facing some issues like mentioned below. ./.libs/libceph_filestore.so: undefined reference to `tracepoint_dlopen' Compiling with -llttng-ust is not resolving the problem. Seen some threads in devel list before, mentioning this problem. Can anyone take a look and guide me to fix this problem? Haven't made the changes to change the plugin name etc... will be making them as part of cleanup.

Benjamin Cc: Loic Dachary; ceph-devel; Sage Weil Subject: RE: loadable objectstore Hi Matt, Majority of the changes are segregating the files to corresponding shared object and creating a factory object. And the naming is mostly taken from Erasure-coding plugins. Want a good naming convention :-), hence a preliminary review. Do agree, we have lot of loadable interfaces, and I think we are in the way of making them on-demand (if possible) loadable modules. Varada -----Original Message----- From: Matt W.
