With CONFIG_MTD=m and CONFIG_CRAMFS=y, we now get a link failure: fs/cramfs/inode.o: In function `cramfs_mount': inode.c:(.text+0x220): undefined reference to `mount_mtd' fs/cramfs/inode.o: In function `cramfs_mtd_fill_super': inode.c:(.text+0x6d8): undefined reference to `mtd_point' inode.c:(.text+0xae4): undefined reference to `mtd_unpoint' This adds a more specific Kconfig dependency to avoid the broken configuration. Alternatively we could make CRAMFS itself depend on "MTD || !MTD" with a similar result.

This reverts commits 5c9d2d5c, c7da82b8, and e7fe7b5c. We'll probably need to revisit this, but basically we should not complicate the get_user_pages_fast() case, and checking the actual page table protection key bits will require more care anyway, since the protection keys depend on the exact state of the VM in question. Particularly when doing a "remote" page lookup (ie in somebody elses VM, not your own), you need to be much more careful than this was. Dave Hansen says: "So, the underlying bug here is that we now a get_user_pages_remote() and then go ahead and do the p*_access_permitted() checks against the current PKRU. This was introduced recently with the addition of the new p??_access_permitted() calls. We have checks in the VMA path for the "remote" gups and we avoid consulting PKRU for them. This got missed in the pkeys selftests because I did a ptrace read, but not a *write*. I also didn't explicitly test it against something where a COW needed to be done" It's also not entirely clear that it makes sense to check the protection key bits at this level at all. But one possible eventual solution is to make the get_user_pages_fast() case just abort if it sees protection key bits set, which makes us fall back to the regular get_user_pages() case, which then has a vma and can do the check there if we want to. We'll see. Somewhat related to this all: what we _do_ want to do some day is to check the PAGE_USER bit - it should obviously always be set for user pages, but it would be a good check to have back. Because we have no generic way to test for it, we lost it as part of moving over from the architecture-specific x86 GUP implementation to the generic one in commit e585513b ("x86/mm/gup: Switch GUP to the generic get_user_page_fast() implementation").

Commit d8f532d2 ("xprtrdma: Invoke rpcrdma_reply_handler directly from RECV completion") introduced a performance regression for NFS I/O small enough to not need memory registration. In multi- threaded benchmarks that generate primarily small I/O requests, IOPS throughput is reduced by nearly a third. This patch restores the previous level of throughput. Because workqueues are typically BOUND (in particular ib_comp_wq, nfsiod_workqueue, and rpciod_workqueue), NFS/RDMA workloads tend to aggregate on the CPU that is handling Receive completions. The usual approach to addressing this problem is to create a QP and CQ for each CPU, and then schedule transactions on the QP for the CPU where you want the transaction to complete. The transaction then does not require an extra context switch during completion to end up on the same CPU where the transaction was started. This approach doesn't work for the Linux NFS/RDMA client because currently the Linux NFS client does not support multiple connections per client-server pair, and the RDMA core API does not make it straightforward for ULPs to determine which CPU is responsible for handling Receive completions for a CQ. So for the moment, record the CPU number in the rpcrdma_req before the transport sends each RPC Call. Then during Receive completion, queue the RPC completion on that same CPU. Additionally, move all RPC completion processing to the deferred handler so that even RPCs with simple small replies complete on the CPU that sent the corresponding RPC Call.

The following deadlock can occur between a process waiting for a client to initialize in while walking the client list during nfsv4 server trunking detection and another process waiting for the nfs_clid_init_mutex so it can initialize that client: Process 1 Process 2 --------- --------- spin_lock(&nn->nfs_client_lock); list_add_tail(&CLIENTA->cl_share_link, &nn->nfs_client_list); spin_unlock(&nn->nfs_client_lock); spin_lock(&nn->nfs_client_lock); list_add_tail(&CLIENTB->cl_share_link, &nn->nfs_client_list); spin_unlock(&nn->nfs_client_lock); mutex_lock(&nfs_clid_init_mutex); nfs41_walk_client_list(clp, result, cred); nfs_wait_client_init_complete(CLIENTA); (waiting for nfs_clid_init_mutex) Make sure nfs_match_client() only evaluates clients that have completed initialization in order to prevent that deadlock. This patch also fixes v4.0 trunking behavior by not marking the client NFS_CS_READY until the clientid has been confirmed.

Yuval Mintz says: ==================== net: sched: Make qdisc offload uapi uniform Several qdiscs can already be offloaded to hardware, but there's an inconsistecy in regard to the uapi through which they indicate such an offload is taking place - indication is passed to the user via TCA_OPTIONS where each qdisc retains private logic for setting it. The recent addition of offloading to RED in 602f3baf ("net_sch: red: Add offload ability to RED qdisc") caused the addition of yet another uapi field for this purpose - TC_RED_OFFLOADED. For clarity and prevention of bloat in the uapi we want to eliminate said added uapi, replacing it with a common mechanism that can be used to reflect offload status of the various qdiscs. The first patch introduces TCA_HW_OFFLOAD as the generic message meant for this purpose. The second changes the current RED implementation into setting the internal bits necessary for passing it, and the third removes TC_RED_OFFLOADED as its no longer needed. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Following the previous patch, RED is now using the new uniform uapi for indicating it's offloaded. As a result, TC_RED_OFFLOADED is no longer utilized by kernel and can be removed [as it's still not part of any stable release].

Let RED utilize the new internal flag, TCQ_F_OFFLOADED, to mark a given qdisc as offloaded instead of using a dedicated indication. Also, change internal logic into looking at said flag when possible.

Qdiscs can be offloaded to HW, but current implementation isn't uniform. Instead, qdiscs either pass information about offload status via their TCA_OPTIONS or omit it altogether. Introduce a new attribute - TCA_HW_OFFLOAD that would form a uniform uAPI for the offloading status of qdiscs.

Igor Russkikh says: ==================== net: aquantia: Atlantic driver 12/2017 updates The patchset contains important hardware fix for machines with large MRRS and couple of improvement in stats and capabilities reporting patch v3: - Fixed patch #7 after Andrew's finding. NIC level stats actually have to be cleaned only on hw struct creation (and this is done in kzalloc). On each hwinit we only have to reset link state to make sure hw stats update will not increment nic stats during init. patch v2: - split into more detailed commits Comment from David on wrong defines case will be submitted separately later ==================== Signed-off-by: NDavid S.

On very first start we should read out current HW counter values to make diff based calculations later. This also should be done each time NIC gets down/up or wakes up after sleep state.
