2020-10-21xfs: fix fallocate functions when rtextsize is larger than 1Darrick J. Wong3-18/+46
In commit fe341eb151ec, I forgot that xfs_free_file_space isn't strictly a "remove mapped blocks" function. It is actually a function to zero file space by punching out the middle and writing zeroes to the unaligned ends of the specified range. Therefore, putting a rtextsize alignment check in that function is wrong because that breaks unaligned ZERO_RANGE on the realtime volume. Furthermore, xfs_file_fallocate already has alignment checks for the functions require the file range to be aligned to the size of a fundamental allocation unit (which is 1 FSB on the data volume and 1 rt extent on the realtime volume). Create a new helper to check fallocate arguments against the realtiem allocation unit size, fix the fallocate frontend to use it, fix free_file_space to delete the correct range, and remove a now redundant check from insert_file_space. NOTE: The realtime extent size is not required to be a power of two!

2020-10-21mptcp: depends on IPV6 but not as a moduleMatthieu Baerts1-1/+1
Like TCP, MPTCP cannot be compiled as a module. Obviously, MPTCP IPv6' support also depends on CONFIG_IPV6. But not all functions from IPv6 code are exported. To simplify the code and reduce modifications outside MPTCP, it was decided from the beginning to support MPTCP with IPv6 only if CONFIG_IPV6 was built inlined. That's also why CONFIG_MPTCP_IPV6 was created. More modifications are needed to support CONFIG_IPV6=m. Even if it was not explicit, until recently, we were forcing CONFIG_IPV6 to be built-in because we had "select IPV6" in Kconfig. Now that we have "depends on IPV6", we have to explicitly set "IPV6=y" to force CONFIG_IPV6 not to be built as a module. In other words, we can now only have CONFIG_MPTCP_IPV6=y if CONFIG_IPV6=y. Note that the new dependency might hide the fact IPv6 is not supported in MPTCP even if we have CONFIG_IPV6=m. But selecting IPV6 like we did before was forcing it to be built-in while it was maybe not what the user wants.

2020-10-21PCI: vmd: Update VMD PM to correctly use generic PCI PMJon Derrick1-2/+0
The pci_save_state() call in vmd_suspend() can be performed by pci_pm_suspend_irq(). This also allows VMD to benefit from the call into pci_prepare_to_sleep(). The pci_restore_state() call in vmd_resume() was restoring state after pci_pm_resume()::pci_restore_standard_config() had already restored state. It's also been suspected that the config state should have been restored before re-requesting IRQs instead of afterwards. Remove the pci_save_state()/pci_restore_state() calls in vmd_suspend()/vmd_resume() to allow proper flow through generic PCI core Power Management code.
