From 8cf9864b1382851d90c7c505f8441c8928f1469e Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Mon, 22 Oct 2012 09:04:31 -0300 Subject: mm/slob: Use free_page instead of put_page for page-size kmalloc allocations When freeing objects, the slob allocator currently free empty pages calling __free_pages(). However, page-size kmallocs are disposed using put_page() instead. It makes no sense to call put_page() for kernel pages that are provided by the object allocator, so we shouldn't be doing this ourselves. This is based on: commit d9b7f22623b5fa9cc189581dcdfb2ac605933bf4 Author: Glauber Costa slub: use free_page instead of put_page for freeing kmalloc allocation Cc: Christoph Lameter Cc: Pekka Enberg Cc: Matt Mackall Acked-by: Glauber Costa Signed-off-by: Ezequiel Garcia Signed-off-by: Pekka Enberg --- mm/slob.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'mm/slob.c') diff --git a/mm/slob.c b/mm/slob.c index fffbc820774..e7d790127e4 100644 --- a/mm/slob.c +++ b/mm/slob.c @@ -500,7 +500,7 @@ void kfree(const void *block) unsigned int *m = (unsigned int *)(block - align); slob_free(m, *m + align); } else - put_page(sp); + __free_pages(sp, compound_order(sp)); } EXPORT_SYMBOL(kfree); -- cgit v1.2.3
