perf cgroup: Maintain cgroup hierarchy

2020-04-03T12:37:55Z

Each cgroup is kept in the perf_env's cgroup_tree sorted by the cgroup id. Hist entries have cgroup id can compare it directly and later it can be used to find a group name using this tree.

tools lib api fs: Move cgroupsfs_find_mountpoint()

2020-03-04T13:34:09Z

Move it from tools/perf/util/cgroup.c as it can be used by other places. Note that cgroup filesystem is different from others since it's usually mounted separately (in v1) for each subsystem. I just copied the code with a little modification to pass a name of subsystem.

perf auxtrace: Uninline functions that touch perf_session

2019-09-01T01:24:10Z

So that we don't carry the session.h include directive in auxtrace.h, which in turn opens a can of worms of files that were getting all sorts of things via that include, fix them all.

perf tools: Remove perf.h from source files not needing it

2019-08-29T20:38:32Z

With the movement of lots of stuff out of perf.h to other headers we ended up not needing it in lots of places, remove it from those places.

perf evlist: Rename struct perf_evlist to struct evlist

2019-07-29T21:34:42Z

Rename struct perf_evlist to struct evlist, so we don't have a name clash when we add struct perf_evlist in libperf.

perf tools: Use zfree() where applicable

2019-07-09T13:13:27Z

In places where the equivalent was already being done, i.e.: free(a); a = NULL; And in placs where struct members are being freed so that if we have some erroneous reference to its struct, then accesses to freed members will result in segfaults, which we can detect faster than use after free to areas that may still have something seemingly valid.

perf cgroup: Make evlist__find_cgroup() more compact

2018-06-04T13:28:50Z

By taking advantage that __get() routines return the pointer to the object for which a reference count is being get.
