Description Tereza Cerna 2015-08-03 12:01:48 UTC

There "transparent_hugepage" is in /etc/default/grub

# cat /etc/default/grub | grep GRUB_CMDLINE_LINUX=
GRUB_CMDLINE_LINUX="console=tty0 elevator=noop crashkernel=auto rd.lvm.lv=rhel_sheep-6/root rd.lvm.lv=rhel_sheep-6/swap console=ttyS0 transparent_hugepage=never"

and "transparent_hugepages" in /usr/lib/tuned/*/tuned.conf

# grep -ri transparent /usr/lib/tuned/*/tuned.conf 
/usr/lib/tuned/network-latency/tuned.conf:transparent_hugepages=never
/usr/lib/tuned/oracle/tuned.conf:transparent_hugepages=never

I think that it is confusing. Please add alias for transparent_hugepages into tuned.
