This fixes a problem that the system is cool, while the fan devices are left running on full speed after boot, if fan device is registered after thermal zone device.

In this case, we need specially handling for the first thermal_zone_device_update(). Both thermal core framework and step_wise governor is enhanced to handle this. And since the step_wise governor is the only one that uses trends, so it's the only thermal governor that needs to be updated.

However, once the header (envelope) is written to the socket, our peer learns data_len and sets itself to expect at least data_len bytes to follow front or front+middle. If ceph_msg_revoke() is called while the messenger is sending message's data portion, anything we send after that call is counted by the OSD towards the now revoked message's data portion. The effects vary, the most common one is the eventual hang - higher layers get stuck waiting for the reply to the message that was sent out after ceph_msg_revoke() returned and treated by the OSD as a bunch of data bytes. This is what Matt ran into. (2) Flat out zeroing con->out_kvec_bytes worth of bytes to handle kvecs is wrong. If ceph_msg_revoke() is called before the tag is sent out or while the messenger is sending the header, we will get a connection reset, either due to a bad tag (0 is not a valid tag) or a bad header CRC, which kind of defeats the purpose of revoke. Currently the kernel client refuses to work with header CRCs disabled, but that will likely change in the future, making this even worse. (3) con->out_skip is not reset on connection reset, leading to one or more spurious connection resets if we happen to get a real one between con->out_skip is set in ceph_msg_revoke() and before it's cleared in write_partial_skip(). Fixing (1) and (3) is trivial. The idea behind fixing (2) is to never zero the tag or the header, i.e. send out tag+header regardless of when ceph_msg_revoke() is called. That way the header is always correct, no unnecessary resets are induced and revoke stands ready for disabled CRCs. Since ceph_msg_revoke() rips out con->out_msg, introduce a new "message out temp" and copy the header into it before sending.

Set up additional fields in svcxprt_rdma to track these resources. The max_requests fields are elements of the RPC-over-RDMA protocol, so they should be u32. To ensure that unsigned arithmetic is used everywhere, some other fields in the svcxprt_rdma struct are updated.

It uses GFP_KERNEL so the allocator tries hard, and may sleep. But I'm about to add a call to svc_rdma_post_recv() from a function that may not sleep. Since all svc_rdma_post_recv() call sites can tolerate its failure, allow it to fail if the page allocator returns nothing. Longer term, receive buffers, being a finite resource per-connection, should be pre-allocated and re-used.

That makes allocating one of these from a kmem_cache more likely to fail in situations when system memory is exhausted. Since I'm about to add a caller where this allocation must always work _and_ it cannot sleep, pre-allocate ctxts for each connection. Another motivation for this change is that NFSv4.x servers are required by specification not to drop NFS requests. Pre-allocating memory resources reduces the likelihood of a drop.
