mm: Remove the BOUNCE config option

[PATCH] mm: Remove the BOUNCE config option

Posted by Huacai Chen 3 months, 4 weeks ago

Commit eeadd68e2a5f6bfe0bf10 ("block: remove bounce buffering support")
remove block/bounce.c but left the BOUNCE config option. Now this option
has no users, so remove it.
