 "Here are a few hopefully uncontroversial fixes:

   - Use RCU_INIT_POINTER() when initializing rcu protected members in
     task_struct to fix sparse warnings.

   - Add pidfd_fdinfo_test binary to .gitignore file"

Pull kselftest update from Shuah Khan:
 "This consists of a cleanup patch to undo changes to global .gitignore
  that added selftests/lkdtm objects and add them to a local
  selftests/lkdtm/.gitignore.

  Summary of Linus's comments on local vs. global gitignore scope:

   - Keep local gitignore patterns in local files.

   - Put only global gitignore patterns in the top-level gitignore file.

  Local scope keeps things much better separated. It also incidentally
  means that if a directory gets renamed, the gitignore file continues
  to work unless in the case of renaming the actual files themselves
  that are named in the gitignore"

2020-03-02T15:39:39+00:00

Commit 68ca0fd272da ("selftest/lkdtm: Don't pollute 'git status'")
introduced patterns for git to ignore files generated in
tools/testing/selftests/lkdtm/

Use local .gitignore file instead of using the root one.

perf annotate: Fix segfault with source toggle

2020-02-27T14:47:23+00:00

While rendering annotate browser from perf report tui, we keep track
of total number of lines(asm + source) in annotation->nr_entries and
total number of asm lines in annotation->nr_asm_entries. But we don't
reset them before starting. Thus if user annotates same function
multiple times, we restart incrementing these fields with old values.

This causes a segfault when user tries to toggle source code after
annotating same function multiple times. Fix it.

perf annotate: Simplify disasm_line allocation and freeing code

2020-02-27T14:07:13+00:00

We are allocating disasm_line object in annotation_line__new() instead
of disasm_line__new(). Similarly annotation_line__delete() is actually
freeing disasm_line object as well. This complexity is because of
privsize.  But we don't need privsize anymore so get rid of privsize and
simplify disasm_line allocation and freeing code.
