It's a bool so this shouldn't matter... not needed.
My mm/Kconfig has:
config ZSMALLOC tristate "Memory allocator for compressed pages" depends on MMU
which I think means it can be modular, no?
ack. I misread it.
Randy means that ZSMALLOC_PGTABLE_MAPPING is a bool, so I think hch's patch is wrong ... if ZSMALLOC is 'm' then ZSMALLOC_PGTABLE_MAPPING would become 'n' instead of 'y'.
sigh, I wish that I had meant that. :)
thanks.
