2019-07-08libceph: bump CEPH_MSG_MAX_DATA_LEN (again)Ilya Dryomov1-2/+4

2019-07-08libceph: rename r_unsafe_item to r_private_itemIlya Dryomov1-1/+1

2019-07-08ceph: more precise CEPH_CLIENT_CAPS_PENDING_CAPSNAPYan, Zheng1-1/+1
Client uses this flag to tell mds if there is more cap snap need to flush. It's mainly for the case that client needs to re-send cap/snap flushes after mds failover, but CEPH_CAP_ANY_FILE_WR on corresponding inodes are all released before mds failover.

2019-07-08iversion: add a routine to update a raw value with a larger oneJeff Layton1-0/+24
Under ceph, clients can be independently updating iversion themselves, while working under comprehensive sets of caps on an inode. In that situation we always want to prefer the largest value of a change attribute. Add a new function that will update a raw value with a larger one, but otherwise leave it alone.

2019-07-07timer: Document TIMER_PINNEDPeter Xu1-8/+19
The flag hints the user that the pinned timers will always be run on a static CPU (because that should be what "pinned" means...) but that's not the truth, at least with the current implementation. For example, currently if a pinned timer is set up but later mod_timer() upon the pinned timer is invoked, mod_timer() will still try to queue the timer on the current processor and migrate the timer if necessary. Document it a bit with the definition of TIMER_PINNED so that all future users will use it correctly.

2019-07-07net/mlx5: Introduce VHCA tunnel device capabilityMax Gurtovoy1-2/+4
When using the device emulation feature (introduced in Bluefield-1 SOC), a privileged function (the device emulation manager) will be able to create a channel to execute commands on behalf of the emulated function. This channel will be a general object of type VHCA_TUNNEL that will have a unique ID for each emulated function. This ID will be passed in each cmd that will be issued by the emulation SW in a well known offset in the command header. This channel is needed since the emulated function doesn't have a normal command interface to the HCA HW, but some basic configuration for that function is needed (e.g. initialize and enable the HCA). For that matter, a specific command-set was defined and only those commands will be issued by the HCA.

We often see various error conditions with NFS4.x that show up with a very high operation count all completing with tk_status < 0 in a short period of time. Add a count to rpc_iostats to record on a per-op basis the ops that complete in this manner, which will enable lower overhead diagnostics.

2019-07-06NFS: send state management on a single connection.NeilBrown1-0/+1
With NFSv4.1, different network connections need to be explicitly bound to a session. During session startup, this is not possible so only a single connection must be used for session startup. So add a task flag to disable the default round-robin choice of connections (when nconnect > 1) and force the use of a single connection. Then use that flag on all requests for session management - for consistence, include NFSv4.0 management (SETCLIENTID) and session destruction Reported-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>

If the client detects that close-to-open cache consistency has been violated, and that the file or directory has been changed on the server, then do a cache invalidation when we're done working with the file. The reason we don't do an immediate cache invalidation is that we want to avoid performance problems due to false positives.

2019-07-06ACPI: PM: Make acpi_sleep_state_supported() non-staticDexuan Cui1-0/+6
With some upcoming patches to save/restore the Hyper-V drivers related states, a Linux VM running on Hyper-V will be able to hibernate. When a Linux VM hibernates, unluckily we must disable the memory hot-add/remove and balloon up/down capabilities in the hv_balloon driver (drivers/hv/hv_balloon.c), because these can not really work according to the design of the related back-end driver on the host. By default, Hyper-V does not enable the virtual ACPI S4 state for a VM; on recent Hyper-V hosts, the administrator is able to enable the virtual ACPI S4 state for a VM, so we hope to use the presence of the virtual ACPI S4 state as a hint for hv_balloon to disable the aforementioned capabilities. In this way, hibernation will work more reliably, from the user's perspective. By marking acpi_sleep_state_supported() non-static, we'll be able to implement a hv_is_hibernation_supported() API in the always-built-in module arch/x86/hyperv/hv_init.c, and the API will be called by hv_balloon.

This patch adds virtio-pmem driver for KVM guest. Guest reads the persistent memory range information from Qemu over VIRTIO and registers it on nvdimm_bus. It also creates a nd_region object with the persistent memory range information so that existing 'nvdimm/pmem' driver can reserve this into system memory map. This way 'virtio-pmem' driver uses existing functionality of pmem driver to register persistent memory compatible for DAX capable filesystems.
