perf/x86/intel/pt: Remove software double buffering PMU capability

2019-05-03T10:46:20Z

Now that all AUX allocations are high-order by default, the software double buffering PMU capability doesn't make sense any more, get rid of it. In case some PMUs choose to opt out, we can re-introduce it.

Pull io_uring fixes from Jens Axboe: "This is mostly io_uring fixes/tweaks. Most of these were actually done in time for the last -rc, but I wanted to ensure that everything tested out great before including them. The code delta looks larger than it really is, as it's mostly just comment additions/changes. Outside of the comment additions/changes, this is mostly removal of unnecessary barriers. In all, this pull request contains: - Tweak to how we handle errors at submission time. We now post a completion event if the error occurs on behalf of an sqe, instead of returning it through the system call. If the error happens outside of a specific sqe, we return the error through the system call. This makes it nicer to use and makes the "normal" use case behave the same as the offload cases. (me) - Fix for a missing req reference drop from async context (me) - If an sqe is submitted with RWF_NOWAIT, don't punt it to async context. Return -EAGAIN directly, instead of using it as a hint to do async punt.

iov_iter: fix iov_iter_type

2019-05-01T14:38:47Z

Commit 875f1d0769cd ("iov_iter: add ITER_BVEC_FLAG_NO_REF flag") introduces one extra flag of ITER_BVEC_FLAG_NO_REF, and this flag is stored into iter->type. However, iov_iter_type() doesn't consider the new added flag, fix it by masking this flag in iov_iter_type().

tracing: Fix buffer_ref pipe ops

2019-04-26T15:44:39Z

This fixes multiple issues in buffer_pipe_buf_ops: - The ->steal() handler must not return zero unless the pipe buffer has the only reference to the page. But generic_pipe_buf_steal() assumes that every reference to the pipe is tracked by the page's refcount, which isn't true for these buffers - buffer_pipe_buf_get(), which duplicates a buffer, doesn't touch the page's refcount. Fix it by using generic_pipe_buf_nosteal(), which refuses every attempted theft. It should be easy to actually support ->steal, but the only current users of pipe_buf_steal() are the virtio console and FUSE, and they also only use it as an optimization. So it's probably not worth the effort. - The ->get() and ->release() handlers can be invoked concurrently on pipe buffers backed by the same struct buffer_ref. Make them safe against concurrency by using refcount_t. - The pointers stored in ->private were only zeroed out when the last reference to the buffer_ref was dropped. As far as I know, this shouldn't be necessary anyway, but if we do it, let's always do it.
