CONFIG_SCHEDSTATS disabled in kernel
Last modified: 2013-11-04 15:26:25 EST
Description of problem:
CONFIG_SCHEDSTATS is disabled in FC19 kernel
The optional has miniscule overhead, but is quite useful to analyze performance problems and should be enabled by default.
Version-Release number of selected component (if applicable):
grep CONFIG_SCHEDSTATS /boot/config-$(uname -r)
Steps to Reproduce:
That's what the Kconfig option says, yes. It seems in practice the overhead isn't minuscule, though I don't have the direct results.
