perf stat:
. Add --interval-clear option, to provide a 'watch' like printing (Jiri Olsa)
. Fix metric column header display alignment (Jiri Olsa)
. Improve error messages for default attributes, providing better output
for error in command lines such as:
$ perf stat -T
Cannot set up transaction events
event syntax error: '..cycles,cpu/cycles-t/,cpu/tx-start/,cpu/el-start/,cpu/cycles-ct/}'
\___ unknown term
Where the "event syntax error" line now appears (Jiri Olsa)
perf script:
. Show hw-cache events too (Seeteena Thoufeek)
perf c2c:
. Fix data dependency problem in layout of 'struct c2c_hist_entry', where
its member 'struct hist_entry' must be at the end because it has a ZLA
as its last member, that gets space when handling callchains (Jiri Olsa)
Core:
- We cannot assume that a 'struct perf_evsel' is to be obtained from a
container_of operation on a 'struct hists' as there are tools, such as
'perf c2c' that uses 'struct hist' instances without having them in
container structs that also have 'struct perf_evsel' in a particular
layout, so provide a different way of figuring out if a 'struct hists'
and 'struct hist_entry' have callchains (Arnaldo Carvalho de Melo)
- Fix error index in the PMU event parser, so that error messages can
point to the problematic token (Jiri Olsa)

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
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.
