The patch titled thp: don't alloc harder for gfp nomemalloc even if nowait has been removed from the -mm tree. Its filename was thp-dont-alloc-harder-for-gfp-nomemalloc-even-if-nowait.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: thp: don't alloc harder for gfp nomemalloc even if nowait From: Andrea Arcangeli <aarcange@xxxxxxxxxx> Not worth throwing away the precious reserved free memory pool for allocations that can fail gracefully (either through mempool or because they're transhuge allocations later falling back to 4k allocations).
