* netlink: add reference of module in netlink_dump_startGao feng2012-10-071-4/+16
| | | | | | | | | | | | | | | | | | | | | | | | I get a panic when I use ss -a and rmmod inet_diag at the same time. It's because netlink_dump uses inet_diag_dump which belongs to module inet_diag. I search the codes and find many modules have the same problem. We need to add a reference to the module which the cb->dump belongs to. Thanks for all help from Stephen,Jan,Eric,Steffen and Pablo. Change From v3: change netlink_dump_start to inline,suggestion from Pablo and Eric. Change From v2: delete netlink_dump_done,and call module_put in netlink_dump and netlink_sock_destruct.

(2) I found that c6x was missing some __KERNEL__ guards in its asm/signal.h. Mark Salter pointed me at a tree with a patch to remove that file entirely and use the asm-generic variant instead. (3) Lastly, m68k turned out to have a header installation problem due to it lacking a kvm_para.h file. The conditional installation bits for linux/kvm_para.h, linux/kvm.h and linux/a.out.h weren't very well specified - and didn't work if an arch didn't have the asm/ version of that file, but there *was* an asm-generic/ version. It seems the "ifneq $((wildcard ...),)" for each of those three headers in include/kernel/Kbuild is invoked twice during header installation, and the second time it matches on the just installed asm-generic/kvm_para.h file and thus incorrectly installs linux/kvm_para.h as well. Most arches actually have an asm/kvm_para.h, so this wasn't detectable in those." * 'uapi-prep' of git://git.infradead.org/users/dhowells/linux-headers: UAPI: Fix conditional header installation handling (notably kvm_para.h on m68k) c6x: remove c6x signal.h UAPI: Split compound conditionals containing __KERNEL__ in Arm64 UAPI: Fix the guards on various asm/unistd.h files c6x: make dsk6455 the default config
| * UAPI: Fix conditional header installation handling (notably kvm_para.h on m68k)David Howells2012-10-041-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The m68k arch doesn't have a kvm_para.h (unlike most or maybe all other arches), but there is one in asm-generic. This means that: ifneq ($(wildcard $(srctree)/arch/$(SRCARCH)/include/asm/kvm_para.h \ $(srctree)/include/asm-$(SRCARCH)/kvm_para.h \ $(INSTALL_HDR_PATH)/include/asm-*/kvm_para.h),) header-y += kvm_para.h endif gets it wrong because it is invoked twice during the header installation - and on the second occasion, asm-generic/kvm_para.h has been installed in usr/, thus triggering a attempt to install asm-m68k/kvm_para.h which will fail. There are three headers with this sort of conditional logic: a.out.h, kvm.h and kvm_para.h. For all three of them, change the logic to be something like: ifneq ($(wildcard $(srctree)/arch/$(SRCARCH)/include/asm/kvm_para.h \ $(srctree)/arch/$(SRCARCH)/include/uapi/asm/kvm_para.h),) which finds the header in only the two places it should be found, and doesn't get incorrectly triggered by the installation of asm-generic's version.

If the nbd-server supports discard, it will send NBD_FLAG_SEND_TRIM to the client. The client will then set the flag in the kernel via NBD_SET_FLAGS, which tells the kernel to enable discards for the device (QUEUE_FLAG_DISCARD). If discard support is enabled, then when the nbd client system receives a discard request, this will be passed along to the nbd-server. When the discard request is received by the nbd-server, it will perform: fallocate(.. FALLOC_FL_PUNCH_HOLE ..) To punch a hole in the backend storage, which is no longer needed.

This allows the nbd-client to set the device flags (to enable read-only mode, or enable discard support, etc.). Flags are typically specified by the nbd-server. During the negotiation phase of the nbd connection, the server sends its flags to the client. The client then uses NBD_SET_FLAGS to inform the kernel of the options. Also included is a one-line fix to debug output for the set-timeout ioctl.

For example a custom algorithm could be used to manage alignment requirements. As I can't predict all the possible requirements/needs for all allocation uses cases, I add a "free" field 'void *data' to pass any needed information to the allocation function. For example 'data' could be used to handle a structure where you store the alignment, the expected memory bank, the requester device, or any information that could influence the allocation algorithm. An usage example may look like this: struct my_pool_constraints { int align; int bank; ... }; unsigned long my_custom_algo(unsigned long *map, unsigned long size, unsigned long start, unsigned int nr, void *data) { struct my_pool_constraints *constraints = data; ... deal with allocation contraints ... return the index in bitmap where perform the allocation } void create_my_pool() { struct my_pool_constraints c; struct gen_pool *pool = gen_pool_create(...); gen_pool_add(pool, ...); gen_pool_set_algo(pool, my_custom_algo, &c); } Add of best-fit algorithm function: most of the time best-fit is slower then first-fit but memory fragmentation is lower. The random buffer allocation/free tests don't show any arithmetic relation between the allocation time and fragmentation but the best-fit algorithm is sometime able to perform the allocation when the first-fit can't. This new algorithm help to remove static allocations on ESRAM, a small but fast on-chip RAM of few KB, used for high-performance uses cases like DMA linked lists, graphic accelerators, encoders/decoders. On the Ux500 (in the ARM tree) we have define 5 ESRAM banks of 128 KB each and use of static allocations becomes unmaintainable: cd arch/arm/mach-ux500 && grep -r ESRAM . ./include/mach/db8500-regs.h:/* Base address and bank offsets for ESRAM */ ./include/mach/db8500-regs.h:#define U8500_ESRAM_BASE 0x40000000 ./include/mach/db8500-regs.h:#define U8500_ESRAM_BANK_SIZE 0x00020000 ./include/mach/db8500-regs.h:#define U8500_ESRAM_BANK0 U8500_ESRAM_BASE ./include/mach/db8500-regs.h:#define U8500_ESRAM_BANK1 (U8500_ESRAM_BASE + U8500_ESRAM_BANK_SIZE) ./include/mach/db8500-regs.h:#define U8500_ESRAM_BANK2 (U8500_ESRAM_BANK1 + U8500_ESRAM_BANK_SIZE) ./include/mach/db8500-regs.h:#define U8500_ESRAM_BANK3 (U8500_ESRAM_BANK2 + U8500_ESRAM_BANK_SIZE) ./include/mach/db8500-regs.h:#define U8500_ESRAM_BANK4 (U8500_ESRAM_BANK3 + U8500_ESRAM_BANK_SIZE) ./include/mach/db8500-regs.h:#define U8500_ESRAM_DMA_LCPA_OFFSET 0x10000 ./include/mach/db8500-regs.h:#define U8500_DMA_LCPA_BASE (U8500_ESRAM_BANK0 + U8500_ESRAM_DMA_LCPA_OFFSET) ./include/mach/db8500-regs.h:#define U8500_DMA_LCLA_BASE U8500_ESRAM_BANK4 I want to use genalloc to do dynamic allocations but I need to be able to fine tune the allocation algorithm.
