From 396bcc5299c281e9cf1737ad0efcd97be9f83845 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Mon, 6 Apr 2020 20:04:35 -0700 Subject: mm: remove CONFIG_TRANSPARENT_HUGE_PAGECACHE Commit e496cf3d7821 ("thp: introduce CONFIG_TRANSPARENT_HUGE_PAGECACHE") notes that it should be reverted when the PowerPC problem was fixed. The commit fixing the PowerPC problem (953c66c2b22a) did not revert the commit; instead setting CONFIG_TRANSPARENT_HUGE_PAGECACHE to the same as CONFIG_TRANSPARENT_HUGEPAGE. Checking with Kirill and Aneesh, this was an oversight, so remove the Kconfig symbol and undo the work of commit e496cf3d7821.
