[PATCH 03/15] mm/hmm: HMM should have a callback before MM is destroyed v2

by jglisse＠redhat.com

From: Ralph Campbell <rcampbell(a)nvidia.com> The hmm_mirror_register() function registers a callback for when the CPU pagetable is modified. Normally, the device driver will call hmm_mirror_unregister() when the process using the device is finished. However, if the process exits uncleanly, the struct_mm can be destroyed with no warning to the device driver.

[PATCH v2] shm: add split function to shm_vm_ops

by Mike Kravetz

If System V shmget/shmat operations are used to create a hugetlbfs backed mapping, it is possible to munmap part of the mapping and split the underlying vma such that it is not huge page aligned. This will untimately result in the following BUG: kernel BUG at /build/linux-jWa1Fv/linux-4.15.0/mm/hugetlb.c:3310!

A split function was added to vm_operations_struct to determine if a mapping can be split. This was mostly for device-dax and hugetlbfs mappings which have specific alignment constraints. Mappings initiated via shmget/shmat have their original vm_ops overwritten with shm_vm_ops. shm_vm_ops functions will call back to the original vm_ops if needed. Add such a split function to shm_vm_ops.

[PATCH v2 1/3] xen: xenbus_dev_frontend: Fix XS_TRANSACTION_END handling

by Simon Gaiser

Commit fd8aa9095a95 ("xen: optimize xenbus driver for multiple concurrent xenstore accesses") made a subtle change to the semantic of xenbus_dev_request_and_reply() and xenbus_transaction_end(). Before on an error response to XS_TRANSACTION_END xenbus_dev_request_and_reply() would not decrement the active transaction counter. But xenbus_transaction_end() has always counted the transaction as finished regardless of the response. The new behavior is that xenbus_dev_request_and_reply() and xenbus_transaction_end() will always count the transaction as finished regardless the response code (handled in xs_request_exit()). But xenbus_dev_frontend tries to end a transaction on closing of the device if the XS_TRANSACTION_END failed before. Trying to close the transaction twice corrupts the reference count. So fix this by also considering a transaction closed if we have sent XS_TRANSACTION_END once regardless of the return code.
