> James Bottomley (1): > module: workaround duplicate section names -tip testing found that this patch breaks the build on x86 if CONFIG_KALLSYMS is disabled: kernel/module.c: In function ‘load_module’: kernel/module.c:2367: error: ‘struct module’ has no member named ‘sect_attrs’ distcc[8269] ERROR: compile kernel/module.c on ph/32 failed make[1]: *** [kernel/module.o] Error 1 make: *** [kernel] Error 2 make: *** Waiting for unfinished jobs.... Commit 1b364bf4 misses the fact that section attributes are only built and dealt with if kallsyms is enabled. The patch below fixes this. ( note, technically speaking this should depend on CONFIG_SYSFS as well but this patch is correct too and keeps the #ifdef less intrusive - in the KALLSYMS && !SYSFS case the code is a NOP. ) Signed-off-by: Ingo Molnar <mingo@elte.hu> [ Replaced patch with a slightly cleaner variation by James Bottomley ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

When an event has no pathname, there's no need to pad it with a null byte and therefore generate an inotify_event sized block of zeros.

The root cause is a duplicate section name (.text); is this legal? [ Amerigo Wang: "AFAIK, yes." ] However, there's a problem with commit 6d760133 in that if you fail to allocate a mod->sect_attrs (in this case it's null because of the duplication), it still gets used without checking in add_notes_attrs() This should fix it [ This patch leaves other problems, particularly the sections directory, but recent parisc toolchains seem to produce these modules and this prevents a crash and is a minimal change -- RR ] Signed-off-by: James Bottomley <James.Bottomley@suse.de> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Tested-by: Helge Deller <deller@gmx.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

We call lmb_end_of_DRAM() to test whether a DMA mask is ok on a machine without IOMMU, but this function is marked as __init. I don't think there's a clean way to get the top of RAM max_pfn doesn't appear to include highmem or I missed (or we have a bug :-) so for now, let's just avoid having a broken 2.6.31 by making this function non-__init and we can revisit later.

Before the rewrite copy_event_to_user always wrote a terqminating '\0' byte to user space after the filename. Since the rewrite that terminating byte was skipped if your filename is exactly a multiple of event_size. Ouch! So add one byte to name_size before we round up and use clear_user to set userspace to zero like /dev/zero does instead of copying the strange nul_inotify_event. I can't quite convince myself len_to_zero will never exceed 16 and even if it doesn't clear_user should be more efficient and a more accurate reflection of what the code is trying to do.

The are races around the idr storage of inotify watches. It's possible that a watch could be found from sys_inotify_rm_watch() in the idr, but it could be removed from the idr before that code does it's removal. Move the locking and the refcnt'ing so that these have to happen atomically. Signed-off-by: Eric Paris <eparis@redhat.com>

When setting the same GPIO number, multiple IRQ shared requests will be done without freing the previous request. It will also try to free a failed request or an already freed IRQ if 0 was written to the gpio file. All these oops and leaks were fixed with the following solution: keep the previous allocated GPIO (if any) still allocated in case the new request fails. The alternative solution would desallocate the previous allocated GPIO and set gpio as 0. Signed-off-by: Thadeu Lima de Souza Cascardo <cascardo@holoscopio.com> Signed-off-by: Samuel R. C.
