  perf record: Read from backward ring buffer (2016-05-23 18:22:48 -0300)

----------------------------------------------------------------
perf/core improvements:

User visible:

- Add "srcline_from" and "srcline_to" branch sort keys to 'perf top' and
  'perf report' (Andi Kleen)

Infrastructure:

- Make 'perf trace' auto-attach fd->name and ptr->name beautifiers based
  on the name of syscall arguments, this way new syscalls that have
  'const char * (path,pathname,filename)' will use the fd->name beautifier
  (vfs_getname perf probe, if in place) and the 'fd->name' (vfs_getname
  or via /proc/PID/fd/) (Arnaldo Carvalho de Melo)

- Infrastructure to read from a ring buffer in backward write mode (Wang Nan)

Signed-off-by: Arnaldo Carvalho de Melo <acme@...hat.com>

----------------------------------------------------------------
Andi Kleen (1):
      perf report: Add srcline_from/to branch sort keys

Arnaldo Carvalho de Melo (2):
      perf trace: Use the fd->name beautifier as default for "fd" args
      perf trace: Use the ptr->name beautifier as default for "filename" args

Wang Nan (6):
      perf evsel: Add overwrite attribute and check write_backward
      perf evsel: Record fd into perf_mmap
      perf evlist: Add API to pause/resume
      perf record: Prevent reading invalid data in record__mmap_read
      perf record: Rename variable to make code clear
      perf record: Read from backward ring buffer
