linux kernel hugpage config problem #7

Closed Wsine closed 7 years ago

Wsine commented 7 years ago

i use vimdiff config.4.4.32 config.4.4.32.rt to see what is the difference between them.

i found config.rt removed CONFIG_TRANSPARENT_HUGEPATH=y around line 526.

$ diff config.4.4.32 config.4.4.32.rt
526,528d518
< CONFIG_TRANSPARENT_HUGEPAGE=y
< CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS=y
< # CONFIG_TRANSPARENT_HUGEPAGE_MADVISE is not set

i want to know the reason for removing this config option.

looking forward to your answer, thank you.

That is removed because of the rt preempt patch.
