      Pull perf/core improvements from Arnaldo Carvalho de Melo:
      
      User visible changes:
      
      - Wire the callchain unwinding "max-stack" now to 'perf script --max-stack',
        allowing to limit the depth of callchains, possibly reducing processing
        time (Arnaldo Carvalho de Melo)
      
      - Ditto for 'perf trace --max-stack' (Arnaldo Carvalho de Melo)
      
      - Introduce a --min-stack filter for 'perf trace', to show syscalls that
        had a userspace callchain leading to it at least min-stack deep (Arnaldo Carvalho de Melo)
      
      - Make 'perf trace' work with multiple threads and the --duration filter,
        i.e. do not print the start of an interrupted syscall followed by ...
        to print interrupts from other threads, as we need to wait the sys_exit
        syscall tracepoint to calculate the duration, duh. (Arnaldo Carvalho de Melo)
      
        System wide --duration now works as expected:
      
         [root@jouet ~]# trace --duration 100
           152.393 (145.147 ms): Timer/24358 futex(uaddr: 0x7f5ed98e56cc, op: WAIT_BITSET|PRIV|CLKRT, val: 7055125, utime: 0x7f5ecdbfec30, val3: 4294967295) = -1 ETIMEDOUT Connection timed out

      - Now 'perf trace's --max-stack and --min-stack will automatically set
        "--call-graph dwarf", if --call-graph is not present on the command line:
      
         [root@jouet ~]# perf trace -e nanosleep --max-stack 3 usleep 1

         [root@jouet ~]#
      
      - Bump 'perf trace --mmap-pages' for root when using callchains and not
        specifying --mmap-pages explicitely (Arnaldo Carvalho de Melo)
      
      Build fixes:
      
      - The python binding object had missing symbols, to some refactoring
        to fix that (Arnaldo Carvalho de Melo)

           The other fixes an issue on some platforms, where we get probe

           be a problem since we had the worker thread poll for completions,

           successfully probe their NVMe device.  Use a proper IRQ check and
           probe (msi-x -> msi ->legacy), like most other drivers to work
           around this.  Both from Keith.

           space to access the counter prior to initialization.  Also from

      If one uses:

      option in terms of widespread availability is "dwarf".
      
      Further work needed to choose a better alternative, LBR, in capable
      systems.

      perf record: Export record_opts based callchain parsing helper · 0883e820
      Arnaldo Carvalho de Melo authored
      To be able to call it outside option parsing, like when setting a
      default --call-graph parameter in 'perf trace' when just --min-stack is
      used.

      perf trace: Introduce --min-stack filter · 5cf9c84e
      Arnaldo Carvalho de Melo authored
      Counterpart to --max-stack, to help focusing on deeply nested calls. Can
      be combined with --duration, etc.
      
      E.g.:
      
        System wide syscall tracing looking for call stacks longer than 66:
      
        # trace --mmap-pages 32768 --filter-pid 2711 --call-graph dwarf,16384 --min-stack 66
      
        Or more compactly:
      
        # trace -m 32768 --filt 2711 --call dwarf,16384 --min-st 66

      perf trace: Do not print interrupted syscalls when using --duration · e519bd9a
      Arnaldo Carvalho de Melo authored
      With multiple threads, e.g. a system wide trace session, and one syscall is
      midway in a thread and another thread starts another syscall we must print the
      start of the interrupted syscall followed by ..., but that can't be done that
      way when we use the --duration filter, as we have to wait for the syscall exit
      to calculate the duration and decide if it should be filtered, so we have to
      disable the interrupted logic and only print at syscall exit, duh.

      block: loop: fix filesystem corruption in case of aio/dio · a7297a6a
      Ming Lei authored
      Starting from commit e36f6204(block: split bios to max possible length),
      block core starts to split bio in the middle of bvec.
      
      Unfortunately loop dio/aio doesn't consider this situation, and
      always treat 'iter.iov_offset' as zero. Then filesystem corruption
      is observed.
      
      This patch figures out the offset of the base bvevc via
      'bio->bi_iter.bi_bvec_done' and fixes the issue by passing the offset
      to iov iterator.
      
      Fixes: e36f6204 (block: split bios to max possible length)
