Subject: [PATCH 0/7] userfaultfd: enable zeropage support for shmem
Date: Tue, 20 Jun 2017 09:20:45 +0300 [thread overview]
Message-ID: <1497939652-16528-1-git-send-email-rppt@linux.vnet.ibm.com> (raw)
Hi,
These patches enable support for UFFDIO_ZEROPAGE for shared memory.
The first two patches are not strictly related to userfaultfd, they are
just minor refactoring to reduce amount of code duplication.
Mike Rapoport (7):
shmem: shmem_charge: verify max_block is not exceeded before inode update
shmem: introduce shmem_inode_acct_block
userfaultfd: shmem: add shmem_mfill_zeropage_pte for userfaultfd support
userfaultfd: mcopy_atomic: introduce mfill_atomic_pte helper
userfaultfd: shmem: wire up shmem_mfill_zeropage_pte
userfaultfd: report UFFDIO_ZEROPAGE as available for shmem VMAs
userfaultfd: selftest: enable testing of UFFDIO_ZEROPAGE for shmem
