Gal Pressman 6cc9e215eb RDMA/nldev: Add copy-on-fork attribute to get sys command ... The new attribute indicates that the kernel copies DMA pages on fork, hence libibverbs' fork support through madvise and MADV_DONTFORK is not needed. The introduced attribute is always reported as supported since the kernel has the patch that added the copy-on-fork behavior. This allows the userspace library to identify older vs newer kernel versions. Extra care should be taken when backporting this patch as it relies on the fact that the copy-on-fork patch is merged, hence no check for support is added. Don't backport this patch unless you also have the following series: commit 70e806e4e6 ("mm: Do early cow for pinned pages during fork() for ptes") and commit 4eae4efa2c ("hugetlb: do early cow when page pinned on src mm"). Fixes: 70e806e4e6 ("mm: Do early cow for pinned pages during fork() for ptes") Fixes: 4eae4efa2c ("hugetlb: do early cow when page pinned on src mm") Link: https://lore.kernel.org/r/20210418121025.66849-1-galpress@amazon.com Signed-off-by: Gal Pressman <galpress@amazon.com> Reviewed-by: Leon Romanovsky <leonro@nvidia.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>		2021-04-27 15:33:20 -03:00
