Subject: [PATCH 07/42] tracing: Clean up hist_field_flags enum
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.14/older/patches-4.14.6-rt7.tar.xz
|
|
|
|
As we add more flags, specifying explicit integers for the flag values
|
|
becomes more unwieldy and error-prone - switch them over to left-shift
|
|
values.
