* PCI: hotplug: Make core explicitly non-modularPaul Gortmaker2016-08-243-24/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code is not being built as a module by anyone: obj-$(CONFIG_HOTPLUG_PCI) += pci_hotplug.o [...] pci_hotplug-objs := pci_hotplug_core.o drivers/pci/hotplug/Kconfig:menuconfig HOTPLUG_PCI drivers/pci/hotplug/Kconfig: bool "Support for PCI Hotplug" Remove uses of MODULE_DESCRIPTION(), MODULE_AUTHOR(), MODULE_LICENSE(), etc., so that when reading the driver there is no doubt it is builtin-only. The information is preserved in comments at the top of the file. Remove orphaned exit function in cpci_hotplug_core.c. Note that for non-modular code, module_init() translates to device_initcall(). One could argue that we should use subsys_initcall() here, but for now we stick with runtime equivalence. We would delete module.h and just keep the moduleparam.h include (since the file does use module_param), but there is a try_module_get and module_put pairing that prevents us from doing that.

The information is preserved in comments at the top of the file. Explicitly disallow driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Delete several functions only used by the remove function. Note that for non-modular code, builtin_platform_driver() uses the same init level priority as module_platform_driver(), so this doesn't change init ordering.

Also delete the .remove function, since that doesn't seem to have a sensible use case. With "normal" endpoint drivers, we have in the past set the suppress_bind_attrs bit to make it clear that the use of ".remove" in a builtin driver was deleted, but here for PCI, it seems overkill to jump through the pcie_port_service_driver and into the struct device_driver in order to finally try and do something similar with the bind setting.

| | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 63a4cc24867d, bio->bi_rw contains flags in the lower portion and the op code in the higher portions. This means that old code that relies on manually setting bi_rw is most likely going to be broken. Instead of letting that brokeness linger, rename the member, to force old and out-of-tree code to break at compile time instead of at runtime. No intended functional changes in this commit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit abf545484d31 changed it from an 'rw' flags type to the newer ops based interface, but now we're effectively leaking some bdev internals to the rest of the kernel. Since we only care about whether it's a read or a write at that level, just pass in a bool 'is_write' parameter instead. Then we can also move op_is_write() and friends back under CONFIG_BLOCK protection. Reviewed-by: Mike Christie <mchristi@redhat.com> Signed-off-by: Jens Axboe <axboe@fb.com>

The container and fs parts both have acks from relevant experts. To use the new feature you have to add an F option to your binfmt_misc configuration" From the docs: "The usual behaviour of binfmt_misc is to spawn the binary lazily when the misc format file is invoked. However, this doesn't work very well in the face of mount namespaces and changeroots, so the F mode opens the binary as soon as the emulation is installed and uses the opened image to spawn the emulator, meaning it is always available once installed, regardless of how the environment changes" * tag 'binfmt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/binfmt_misc: binfmt_misc: add F option description to documentation binfmt_misc: add persistent opened binary handler for containers fs: add filp_clone_open API

If you pass in 'F' the binary that runs the emulation will be opened immediately and in future, will be cloned from the open file. The net effect is that the handler survives both changeroots and mount namespace changes, making it easy to work with foreign architecture containers without contaminating the container image with the emulator.

(2) cachefiles_mark_object_inactive() marks the object as being inactive and *only then* reads the i_blocks on the backing inode - but cachefiles_cull() might've managed to delete it by this point. Fix this by making sure cachefiles_mark_object_inactive() gets any data it needs from the backing inode before deactivating the object.
