+Subject: [PATCH] [compiler-rt][sanitizer] Remove linux/scc.h
+
+Linux Kernel has removed scc.h header completely from the source code
+Therefore, we need to remove the usage in compiler-rt/sanitizer too.
+https://github.com/torvalds/linux/commit/64edfa65062dc4509ba75978116b2f6d392346f5#diff-1ca78e598a5041ee51ae795d168435afad598b82a7a0ce80f215993589b96c7c
+
+Without removing it, not only it breaks compiler-rt but also GCC build
+since GCC always builds libsanitizer for linux targets.
+
+After merging this we will need to cherry pick to GCC.
+
+[sanitizer] make git-clang-format happy
+
+git-clang-format tries to ask me to format other code even
+i did not actually write the code.
+Now apply the diff it asks us to do
