Hi, This is v0.12 of the Ceph distributed file system client. Changes since v0.11 include: - mapping_set_error on failed writepage - document correct debugfs mount point - simplified layout/striping ioctls - removed bad kmalloc in writepages - use mempools for writeback allocations where appropriate (*) - fixed a problem with capability, snap metadata writeback - cleaned up f(data)sync wrt metadata writeback (*) There are still some OOM possibilities on writeback in the messenger library. It's possible to avoid this with the careful use of mempools, but I'd like to avoid doing so until it's clear the protocol isn't going to change further. The client seems to be quite stable in a single mds, no snapshot scenario (including recovery from mds, osd restarts). Thorough testing of snapshots and multiple MDSs is coming next. Client authentication (beyond the current host ip checking) is the other main item on the client todo list. As always, I'm very interested in hearing what people would like to see for this to be merged.
