      Pull tracing fix from Steven Rostedt:
       "Masami found a slight bug in his code where he transposed the
        arguments of a call to strpbrk.
        The reason this wasn't detected in our tests is that the only way this
        would transpire is when a kprobe event with a symbol offset is
        attached to a function that belongs to a module that isn't loaded yet.
        When the kprobe trace event is added, the offset would be truncated
        after it was parsed, and when the module is loaded, it would use the
        symbol without the offset (as the nul character added by the parsing
        would not be replaced with the original character)"

      This is failing this check:
                      end = ichdr.freemap[i].base + ichdr.freemap[i].size;
                      if (end < ichdr.freemap[i].base)

                              return __this_address;
      And from the buffer output above, the freemap array is:
      	freemap[0].base = 0x00a0
      	freemap[0].size = 0xdcf4	end = 0xdd94
      	freemap[1].base = 0xfe98
      	freemap[1].size = 0x0168	end = 0x10000
      	freemap[2].base = 0xf0d8
      	freemap[2].size = 0x07e0	end = 0xf8b8
      These all look valid - the block size is 0x10000 and so from the
      last check in the above verifier fragment we know that the end
      of freemap[1] is valid. The problem is that end is declared as:
      	uint16_t	end;
      And (uint16_t)0x10000 = 0. So we have a verifier bug here, not a
      corruption. Fix the verifier to use uint32_t types for the check and
      hence avoid the overflow.

      xfs: print buffer offsets when dumping corrupt buffers · bdec055b
      Darrick J. Wong authored
      Use DUMP_PREFIX_OFFSET when printing hex dumps of corrupt buffers

      This is totally worthless for a sequential dump since we probably only
      care about tracking the buffer offsets and afaik there's no way to
      recover the actual pointer from the hashed value.

      xfs: Fix error code in 'xfs_ioc_getbmap()' · 132bf672
      Christophe JAILLET authored
      In this function, once 'buf' has been allocated, we unconditionally
      return 0.
      However, 'error' is set to some error codes in several error handling
      Before commit 232b5194 ("xfs: simplify the xfs_getbmap interface")
      this was not an issue because all error paths were returning directly,
      but now that some cleanup at the end may be needed, we must propagate the
      error code.
