Hi all, This is a revised version of patch 12 from my series to lock down some follow_pfn vs VM_SPECIAL races:
https://lore.kernel.org/dri-devel/cakwvodnsrsntgpeuqjyaotsktp2dr9208y66hqg_h1e2lkf...@mail.gmail.com/ Stephen reported an issue on HAVE_PCI_LEGACY platforms which this patch set tries to address. Previous patches are all still in linux-next. Stephen, would be awesome if you can give this a spin. Björn/Greg, review on the first patch is needed, I think that's the cleanest approach from all the options I discussed with Greg in this thread: https://lore.kernel.org/dri-devel/cakmk7ugrddrbtj0oyzqqc0cgrqwc2f3tfju9vlfm2jjufaz...@mail.gmail.com/ Cheers, Daniel Cc: Stephen Rothwell <[email protected]> Cc: Jason Gunthorpe <[email protected]> Cc: Kees Cook <[email protected]> Cc: Dan Williams <[email protected]> Cc: Andrew Morton <[email protected]> Cc: John Hubbard <[email protected]> Cc: Jérôme Glisse <[email protected]> Cc: Jan Kara <[email protected]> Cc: Dan Williams <[email protected]> Cc: Greg Kroah-Hartman <[email protected]> Cc: [email protected] Cc: [email protected] Cc: [email protected] Cc: [email protected] Cc: Bjorn Helgaas <[email protected]> Cc: [email protected] Daniel Vetter (2): PCI: also set up legacy files only after sysfs init PCI: Revoke mappings like devmem drivers/pci/pci-sysfs.c | 11 +++++++++++ drivers/pci/proc.c | 1 + 2 files changed, 12 insertions(+) -- 2.30.0
