New features:
- Add PERF_RECORD_NAMESPACES so that the kernel can record information
required to associate samples to namespaces, helping in container
problem characterization.
Now the 'perf record has a --namespace' option to ask for such info,
and when present, it can be used, initially, via a new sort order,
'cgroup_id', allowing histogram entry bucketization by a (device, inode)
based cgroup identifier (Hari Bathini)
- Add --next option to 'perf sched timehist', showing what is the next
thread to run (Brendan Gregg)
Fixes:
- Fix segfault with basic block 'cycles' sort dimension (Changbin Du)
- Add c2c to command-list.txt, making it appear in the 'perf help'
output (Changbin Du)
- Fix zeroing of 'abs_path' variable in the perf hists browser switch
file code (Changbin Du)
- Hide tips messages when -q/--quiet is given to 'perf report' (Namhyung Kim)
Infrastructure:
- Use ref_reloc_sym + offset to setup kretprobes (Naveen Rao)
- Ignore generated files pmu-events/{jevents,pmu-events.c} for git (Changbin Du)
Documentation:
- Document +field style argument support for --field option (Changbin Du)
- Clarify 'perf c2c --stats' help message (Namhyung Kim)

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
