Subject: [PATCH v2 0/2] mm: support NOSIGBUS on fault of mmap
Date: Fri, 4 Jun 2021 00:43:20 -0700 [thread overview]
Message-ID: <1622792602-40459-1-git-send-email-mlin@kernel.org> (raw)
These 2 patches are based on the discussion of "Sealed memfd & no-fault mmap"
at https://bit.ly/3pdwOGR
v2:
- make MAP_NOSIGBUS generic instead of being restricted to shmem
- use do_anonymous_page() to insert zero page
- fix build warnings/errors reported by LKP test robot
v1:
https://lkml.org/lkml/2021/6/1/1076
Ming Lin (2):
mm: make "vm_flags" be an u64
mm: adds NOSIGBUS extension to mmap()
