Subject: [PATCH 07/29] hrtimer: Cleanup hrtimer_mode enum
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.14/older/patches-4.14.15-rt13.tar.xz
|
|
|
|
It's not obvious that the HRTIMER_MODE variants are bit combinations
|
|
because all modes are hard coded constants.
|
|
|
|
Change it so the bit meanings are clear and use the symbols for creating
|
|
modes which combine bits.
|
|
|
|
While at it get rid of the ugly tail comments.
