2020-04-21blk-iocost: Fix error on iocost_ioc_vrate_adjWaiman Long
Systemtap 4.2 is unable to correctly interpret the "u32 (*missed_ppm)[2]" argument of the iocost_ioc_vrate_adj trace entry defined in include/trace/events/iocost.h leading to the following error: /tmp/stapAcz0G0/stap_c89c58b83cea1724e26395efa9ed4939_6321_aux_6.c:78:8: error: expected ‘;’, ‘,’ or ‘)’ before ‘*’ token , u32[]* __tracepoint_arg_missed_ppm That argument type is indeed rather complex and hard to read. Looking at block/blk-iocost.c. It is just a 2-entry u32 array. By simplifying the argument to a simple "u32 *missed_ppm" and adjusting the trace entry accordingly, the compilation error was gone.

2020-04-21KVM: Remove redundant argument to kvm_arch_vcpu_ioctl_runTianjia Zhang
In earlier versions of kvm, 'kvm_run' was an independent structure and was not included in the vcpu structure. At present, 'kvm_run' is already included in the vcpu structure, so the parameter 'kvm_run' is redundant. This patch simplifies the function definition, removes the extra 'kvm_run' parameter, and extracts it from the 'kvm_vcpu' structure if necessary.

2020-04-20vdso/datapage: Use correct clock mode name in commentChristian Brauner
While the explanation for time namespace <-> vdso interactions is very helpful it uses the wrong name in the comment when describing the clock mode making grepping a bit annoying. This seems like an accidental oversight when moving from VCLOCK_TIMENS to VDSO_CLOCKMODE_TIMENS. It seems that 660fd04f9317 ("lib/vdso: Prepare for time namespace support") misspelled VCLOCK_TIMENS as VLOCK_TIMENS which explains why it got missed when VCLOCK_TIMENS became VDSO_CLOCKMODE_TIMENS in 2d6b01bd88cc ("lib/vdso: Move VCLOCK_TIMENS to vdso_clock_modes").

It's not safe to use resources pointed to by the @send_wr of ib_post_send() _after_ that function returns. Those resources are typically freed by the Send completion handler, which can run before ib_post_send() returns. Thus the trace points currently around ib_post_send() in the client's RPC/RDMA transport are a hazard, even when they are disabled.

Intel uses the same family/model for several CPUs. Sometimes the stepping must be checked to tell them apart. On x86 there can be at most 16 steppings. Add a steppings bitmask to x86_cpu_id and a X86_MATCH_VENDOR_FAMILY_MODEL_STEPPING_FEATURE macro and support for matching against family/model/stepping.

2020-04-20dma-pool: add additional coherent pools to map to gfp maskDavid Rientjes
The single atomic pool is allocated from the lowest zone possible since it is guaranteed to be applicable for any DMA allocation. Devices may allocate through the DMA API but not have a strict reliance on GFP_DMA memory. Since the atomic pool will be used for all non-blockable allocations, returning all memory from ZONE_DMA may unnecessarily deplete the zone. Provision for multiple atomic pools that will map to the optimal gfp mask of the device. When allocating non-blockable memory, determine the optimal gfp mask of the device and use the appropriate atomic pool. The coherent DMA mask will remain the same between allocation and free and, thus, memory will be freed to the same atomic pool it was allocated from. __dma_atomic_pool_init() will be changed to return struct gen_pool * later once dynamic expansion is added.

When ESP encapsulation is enabled on a TCP socket, I'm replacing the existing ->sk_destruct callback with espintcp_destruct. We still need to call the old callback to perform the other cleanups when the socket is destroyed. Save the old callback, and call it from espintcp_destruct.

git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux Pull flexible-array member conversion from Gustavo Silva: "The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member convertions) will also help to get completely rid of those sorts of issues. Notice that all of these patches have been baking in linux-next for quite a while now and, 238 more of these patches have already been merged into 5.7-rc1.
