Commit b2b9d3a3f021 ("perf pmu: Support wildcards on pmu name in dynamic
pmu events") gives the following example for wildcarding a subset of
PMUs:
E.g., in a system with the following dynamic pmus:
mypmu_0
mypmu_1
mypmu_2
mypmu_4
perf stat -e mypmu_[01]/<config>/
Since commit f91fa2ae6360 ("perf pmu: Refactor perf_pmu__match()"), only
"*" has been supported, removing the ability to subset PMUs, even though
parse-events.l still supports ? and [] characters.
Fix it by using fnmatch() when any glob character is detected and add a
test which covers that and other scenarios of
perf_pmu__match_ignoring_suffix().

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 reStructuredText markup notation.
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.
