  # HEAD: 144b9152791ffcd038c3b63063999b25780060d8: kcsan: Fix trivial typo in Kconfig help comments (2022-10-18 15:07:33 -0700)

----------------------------------------------------------------
KCSAN updates for v6.2

This series adds instrumentation for memcpy(), memset(), and memmove() for
Clang v16+'s new function names that are used when the -fsanitize=thread
argument is given.  It also fixes objtool warnings from KCSAN's volatile
instrumentation, and fixes a pair of typos in a pair of Kconfig options'
help clauses.

----------------------------------------------------------------
Marco Elver (2):
      kcsan: Instrument memcpy/memset/memmove with newer Clang
      objtool, kcsan: Add volatile read/write instrumentation to whitelist

Ryosuke Yasuoka (1):
      kcsan: Fix trivial typo in Kconfig help comments
