BUG: IPv6 stops working after a while, needs ip ne del command to reset
(originally sent to netdev on aug 6th) IPv6 initially works, but when I leave it alone overnight I'm unable to ping even my default gw. Static global IPv6 addresses configured on both ends. No access lists on either end. Kernel version: 2.6.35 mainline (amd64) and 2.6.33.6. Kernel config: http://pastebi... 13 Aug 2010 14:40

linux-2.6.35+ causes LVM to fail with " device-mapper: version ioctl failed: Inappropriate ioctl for device"
It seems one of these commits in 8357422d4bf33bc2c35884d4016c3fc9efbbc1d2 is causing LVM2 (LVM2.2.02.72) to fail. Previously good logical volumes cannot be mounted anymore, and new one cannot be created. All failed with the error ...

netpoll: use non-BH variant of RCU

[PATCH 8/8] rbd: introduce rados block device (rbd), based on libceph
From: Yehuda Sadeh <yehuda(a)hq.newdream.net> The rados block device (rbd), based on osdblk, creates a block device that is backed by objects stored in the Ceph distributed object storage cluster. Each device consists of a single metadata object and data striped over many data objects. The rbd driver supports r... 13 Aug 2010 14:40

[PATCH 0/8] rados block device and ceph refactor
Hi, The rados block device (rbd) implements a network block device backed by the Ceph distributed object store (think nbd/iSCSI, but distributed and fault tolerant). At the suggestion of Christoph and James, this version of the patchset factors out the common Ceph bits (the network protocol, cluster members... 13 Aug 2010 14:40

[PATCH 3/8] ceph-rbd: messenger and osdc changes for rbd
From: Yehuda Sadeh <yehuda(a)hq.newdream.net> The messenger can send/receive data in bio. This was added so that we wouldn't need to copy the data from the rados block device. We can now have trailing variable sized data for osd ops. Also osd ops encoding is more modular. Signed-off-by: Yehuda Sadeh <yehuda@... 13 Aug 2010 14:40

[PATCH 2/8] ceph-rbd: refactor osdc requests creation functions
From: Yehuda Sadeh <yehuda(a)hq.newdream.net> The osd requests creation are being decoupled from the vino parameter, allowing clients using the osd to use other arbitrary object names that are not necessarily vino based. Also, calc_raw_layout now takes a snap id. Signed-off-by: Yehuda Sadeh <yehuda(a)hq.newdream.n... 13 Aug 2010 14:40

[PATCH 5/8] ceph-rbd: refactor mount related functions, add helpers
From: Yehuda Sadeh <yehuda(a)hq.newdream.net> Removed some functions' static declarations, separated mount operation to __open_session and open_root_dentry for clients that don't need the latter (rbd). Added other helper functions that will be used later in the rbd. Signed-off-by: Yehuda Sadeh <yehuda(a)hq.newdrea... 13 Aug 2010 14:40
