From mboxrd@z Thu Jan 1 00:00:00 1970 Date: Tue, 16 Nov 1999 14:18:58 +0100 (CET) From: Ingo Molnar Subject: [patch] zoned-2.3.28-K2 Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-linux-mm@kvack.org Return-Path: To: MM mailing list , linux-kernel@vger.rutgers.edu Cc: Linus Torvalds , Jeff Garzik List-ID: the latest patchset is at: http://www.redhat.com/~mingo/zoned-2.3.28-K2 this patch is supposed to fix all known problems (including the 16MB kept free thing), let me know if there is still something left. Changes in zoned-2.3.28-K0: - fixed stupid oom bug reported by Jeff and others, introduced in J5 - fixed memory balancing - show_free_areas() bug fixed. - (includes Russell King's procfs fix) Changes in zoned-2.3.28-J5: - further page_alloc.c cleanups/speedups. - Alan and Rogier convinced me to optimize the 'top level zone is empty' case a bit more. - show_free_areas() works again. - some more include file fixes Changes in zoned-2.3.28-H2: - fixed NFS to work out of high memory - tested with moderate load. All NFS caches (directory, symlink, data, etc.) are in high memory. - modules fix ... - page->virtual is filled out for non-highmem pages too, this is a nice speedup in certain cases. - fixed a bug in highmem support which might cause user-datapage corruption in certain cases. Changes in zoned-2.3.28-G5: - this one should actually compile if modules support is turned on ... Changes in zoned-2.3.28-G4: - implemented 'zone chains' zonelist_t and gfp_mask indexed zonelists[] speedups (Linus' idea) to handle fallback zones. This should enable advanced NUMA-style allocations as well. [fallback to different CPUs is possible via changing build_zonelists().] - <=16MB RAM boxes should boot just fine now. - added page->zone for easier deallocation and generic cleanliness. This also helps NUMA. - cleaned up the page-allocator namespace, there are only two 'core' page-allocation functions left: __alloc_pages() and __free_pages_ok(). - modules should compile again. - we are now inlining the 'put_page_testzero()' part of __free_page_ok. This is subtle as page->count for reserved pages is now 'rotating' - this is fine though and lets us to put the rare PageReserved() branch into __free_page_ok(). - cleaned up pgtable.h, split into lowlevel and highlevel parts, this fixes dependencies in mm.h & misc.c. - serial.c didnt clear freshly allocated bootmem - as a result now all bootmem allocations are explicitly cleared, it's not performance critical anyway. - fixed code,data,initmem reporting. - fixed boot task's swapper_pg_dir clearing -- mingo -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
